[doc] rearranges Settings & Engines docs for better readability
We have built up detailed documentation of the *settings* and the *engines* over the past few years. However, this documentation was still spread over various chapters and was difficult to navigate in its entirety. This patch rearranges the Settings & Engines documentation for better readability. To review new ordered docs:: make docs.clean docs.live Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

|
|
||||||
|
|
||||||
With *command engines* administrators can run engines to integrate arbitrary
|
|
||||||
shell commands.
|
|
||||||
|
|
||||||
When creating and enabling a ``command`` engine on a public instance, you must
|
|
||||||
be careful to avoid leaking private data. The easiest solution is to limit the
|
|
||||||
access by setting ``tokens`` as described in section :ref:`private engines`.
|
|
||||||
|
|
||||||
The engine base is flexible. Only your imagination can limit the power of this
|
|
||||||
engine (and maybe security concerns). The following options are available:
|
|
||||||
|
|
||||||
``command``:
|
|
||||||
A comma separated list of the elements of the command. A special token
|
|
||||||
``{{QUERY}}`` tells where to put the search terms of the user. Example:
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|
|
||||||
['ls', '-l', '-h', '{{QUERY}}']
|
|
||||||
|
|
||||||
``delimiter``:
|
|
||||||
A mapping containing a delimiter ``char`` and the *titles* of each element in
|
|
||||||
``keys``.
|
|
||||||
|
|
||||||
``parse_regex``:
|
|
||||||
A dict containing the regular expressions for each result key.
|
|
||||||
|
|
||||||
``query_type``:
|
|
||||||
|
|
||||||
The expected type of user search terms. Possible values: ``path`` and
|
|
||||||
``enum``.
|
|
||||||
|
|
||||||
``path``:
|
|
||||||
Checks if the user provided path is inside the working directory. If not,
|
|
||||||
the query is not executed.
|
|
||||||
|
|
||||||
``enum``:
|
|
||||||
Is a list of allowed search terms. If the user submits something which is
|
|
||||||
not included in the list, the query returns an error.
|
|
||||||
|
|
||||||
``query_enum``:
|
|
||||||
A list containing allowed search terms if ``query_type`` is set to ``enum``.
|
|
||||||
|
|
||||||
``working_dir``:
|
|
||||||
|
|
||||||
The directory where the command has to be executed. Default: ``./``
|
|
||||||
|
|
||||||
``result_separator``:
|
|
||||||
The character that separates results. Default: ``\n``
|
|
||||||
|
|
||||||
The example engine below can be used to find files with a specific name in the
|
|
||||||
configured working directory:
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|
|
||||||
- name: find
|
|
||||||
engine: command
|
|
||||||
command: ['find', '.', '-name', '{{QUERY}}']
|
|
||||||
query_type: path
|
|
||||||
shortcut: fnd
|
|
||||||
delimiter:
|
|
||||||
chars: ' '
|
|
||||||
keys: ['line']

============================
|
|
||||||
Private Engines (``tokens``)
|
|
||||||
============================
|
|
||||||
|
|
||||||
Administrators might find themselves wanting to limit access to some of the
|
|
||||||
enabled engines on their instances. It might be because they do not want to
|
|
||||||
expose some private information through :ref:`offline engines`. Or they would
|
|
||||||
rather share engines only with their trusted friends or colleagues.
|
|
||||||
|
|
||||||
To solve this issue the concept of *private engines* exists.
|
|
||||||
|
|
||||||
|
|
||||||
A new option was added to engines named `tokens`. It expects a list of
|
|
||||||
strings. If the user making a request presents one of the tokens of an engine,
|
|
||||||
they can access information about the engine and make search requests.
|
|
||||||
|
|
||||||
Example configuration to restrict access to the Arch Linux Wiki engine:
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|
|
||||||
- name: arch linux wiki
|
|
||||||
engine: archlinux
|
|
||||||
shortcut: al
|
|
||||||
tokens: [ 'my-secret-token' ]
|
|
||||||
|
|
||||||
|
|
||||||
Unless a user has configured the right token, the engine is going
|
|
||||||
to be hidden from him/her. It is not going to be included in the
|
|
||||||
list of engines on the Preferences page and in the output of
|
|
||||||
`/config` REST API call.
|
|
||||||
|
|
||||||
Tokens can be added to one's configuration on the Preferences page
|
|
||||||
under "Engine tokens". The input expects a comma separated list of
|
|
||||||
strings.
|
|
||||||
|
|
||||||
The distribution of the tokens from the administrator to the users
|
|
||||||
is not carved in stone. As providing access to such engines
|
|
||||||
implies that the admin knows and trusts the user, we do not see
|
|
||||||
necessary to come up with a strict process. Instead,
|
|
||||||
we would like to add guidelines to the documentation of the feature.

Administrators might find themselves wanting to integrate locally running search
|
|
||||||
engines. The following ones are supported for now:
|
|
||||||
|
|
||||||
* `Elasticsearch`_
|
|
||||||
* `Meilisearch`_
|
|
||||||
* `Solr`_
|
|
||||||
|
|
||||||
Each search engine is powerful, capable of full-text search. All of the engines
|
|
||||||
above are added to ``settings.yml`` just commented out, as you have to
|
|
||||||
``base_url`` for all them.
|
|
||||||
|
|
||||||
Please note that if you are not using HTTPS to access these engines, you have to enable
|
|
||||||
HTTP requests by setting ``enable_http`` to ``True``.
|
|
||||||
|
|
||||||
Furthermore, if you do not want to expose these engines on a public instance, you
|
|
||||||
can still add them and limit the access by setting ``tokens`` as described in
|
|
||||||
section :ref:`private engines`.

|
|
||||||
|
|
||||||
MeiliSearch_ is aimed at individuals and small companies. It is designed for
|
|
||||||
small-scale (less than 10 million documents) data collections. E.g. it is great
|
|
||||||
for storing web pages you have visited and searching in the contents later.
|
|
||||||
|
|
||||||
The engine supports faceted search, so you can search in a subset of documents
|
|
||||||
of the collection. Furthermore, you can search in MeiliSearch_ instances that
|
|
||||||
require authentication by setting ``auth_token``.
|
|
||||||
|
|
||||||
Here is a simple example to query a Meilisearch instance:
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|
|
||||||
- name: meilisearch
|
|
||||||
engine: meilisearch
|
|
||||||
shortcut: mes
|
|
||||||
base_url: http://localhost:7700
|
|
||||||
index: my-index
|
|
||||||
enable_http: true
|
|
||||||
|
|
||||||
|
|
||||||
.. _engine elasticsearch:
|
|
||||||
|
|
||||||
Elasticsearch
|
|
||||||
=============
|
|
||||||
|
|
||||||
.. sidebar:: info
|
|
||||||
|
|
||||||

||||||

|
|
||||||
<https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html>`_
|
|
||||||
|
|
||||||
Elasticsearch_ supports numerous ways to query the data it is storing. At the
|
|
||||||
moment the engine supports the most popular search methods (``query_type``):
|
|
||||||
|
|
||||||
- ``match``,
|
|
||||||
- ``simple_query_string``,
|
|
||||||
- ``term`` and
|
|
||||||
- ``terms``.
|
|
||||||
|
|
||||||
If none of the methods fit your use case, you can select ``custom`` query type
|
|
||||||
and provide the JSON payload to submit to Elasticsearch in
|
|
||||||
``custom_query_json``.
|
|
||||||
|
|
||||||
The following is an example configuration for an Elasticsearch_ instance with
|
|
||||||
authentication configured to read from ``my-index`` index.
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|
|
||||||
- name: elasticsearch

|

index: my-index
|

Solr_ is a popular search engine based on Lucene, just like Elasticsearch_. But

|
||||||
instead of searching in indices, you can search in collections.
|
|
||||||
|
|
||||||
This is an example configuration for searching in the collection
|
|
||||||
``my-collection`` and get the results in ascending order.

|
|
||||||
A redis DB can be connected by an URL, in :py:obj:`searx.redisdb` you
|
|
||||||
will find a description to test your redis connection in SerXNG. When using
|
|
||||||
sockets, don't forget to check the access rights on the socket::
|
|
||||||
|
|
||||||
ls -la /usr/local/searxng-redis/run/redis.sock
|
|
||||||
srwxrwx--- 1 searxng-redis searxng-redis ... /usr/local/searxng-redis/run/redis.sock
|
|
||||||
|
|
||||||
In this example read/write access is given to the *searxng-redis* group. To get
|
|
||||||
access rights to redis instance (the socket), your SearXNG (or even your
|
|
||||||
developer) account needs to be added to the *searxng-redis* group.
|
|
||||||
|
|
||||||
``url`` : ``$SEARXNG_REDIS_URL``
|

.. admonition:: Tip for developers
|
|
||||||
|
|

To set up a local redis instance, first set the socket path of the Redis DB
|
|
||||||
in your YAML setting:
|
|
||||||
|
|
||||||
.. code:: yaml
|
|
||||||
|

||||||
redis:
|
|
||||||
url: unix:///usr/local/searxng-redis/run/redis.sock?db=0
|
|
||||||
|
|
||||||
Then use the following commands to install the redis instance ::
|
|
||||||
|
|
||||||
$ ./manage redis.build
|
|
||||||
$ sudo -H ./manage redis.install
|
|
||||||
$ sudo -H ./manage redis.addgrp "${USER}"
|

``request_timeout`` :
|
|
||||||
Global timeout of the requests made to others engines in seconds. A bigger
|
|
||||||
timeout will allow to wait for answers from slow engines, but in consequence
|
|
||||||
will slow SearXNG reactivity (the result page may take the time specified in the
|
|
||||||
timeout to load). Can be override by ``timeout`` in the :ref:`settings engine`.
|
|
||||||
|
|
||||||
``useragent_suffix`` :
|
|
||||||

Define one or more proxies you wish to use, see `httpx proxies`_.
|
|
||||||
If there are more than one proxy for one protocol (http, https),
|
|
||||||
requests to the engines are distributed in a round-robin fashion.
|
|
||||||
|
|
||||||
``source_ips`` :
|
|
||||||
If you use multiple network interfaces, define from which IP the requests must
|
|
||||||
be made. Example:
|
|
||||||
|
|
||||||
* ``0.0.0.0`` any local IPv4 address.
|
|
||||||
* ``::`` any local IPv6 address.
|
|
||||||
* ``192.168.0.1``
|
|
||||||
* ``[ 192.168.0.1, 192.168.0.2 ]`` these two specific IP addresses
|
|
||||||
* ``fe80::60a2:1691:e5a2:ee1f``
|
|
||||||
* ``fe80::60a2:1691:e5a2:ee1f/126`` all IP addresses in this network.
|
|
||||||
* ``[ 192.168.0.1, fe80::/126 ]``
|
|
||||||
|
|
||||||
``retries`` :
|
|
||||||
Number of retry in case of an HTTP error. On each retry, SearXNG uses an
|
|
||||||
different proxy and source ip.
|
|
||||||
|
|
||||||
``enable_http2`` :
|
|
||||||
Enable by default. Set to ``false`` to disable HTTP/2.

|
||||||
``name`` :
|
|
||||||
Name that will be used across SearXNG to define this engine. In settings, on
|
|
||||||
the result page...
|
|
||||||
|
|
||||||
``engine`` :
|
|
||||||
Name of the python file used to handle requests and responses to and from this
|
|
||||||
search engine.
|
|
||||||
|
|
||||||
``shortcut`` :
|
|
||||||
Code used to execute bang requests (in this case using ``!bi``)
|
|
||||||
|
|
||||||
``base_url`` : optional
|
|
||||||
Part of the URL that should be stable across every request. Can be useful to
|
|
||||||
use multiple sites using only one engine, or updating the site URL without
|
|
||||||
touching at the code.
|
|
||||||
|
|
||||||
``send_accept_language_header`` :
|
|
||||||
Several engines that support languages (or regions) deal with the HTTP header
|
|
||||||
``Accept-Language`` to build a response that fits to the locale. When this
|
|
||||||
option is activated, the language (locale) that is selected by the user is used
|
|
||||||
to build and send a ``Accept-Language`` header in the request to the origin
|
|
||||||
search engine.
|
|
||||||
|
|
||||||
.. _engine categories:
|
|
||||||
|
|
||||||
``categories`` : optional
|
|
||||||
Specifies to which categories the engine should be added. Engines can be
|
|
||||||
assigned to multiple categories.
|
|
||||||
|
|
||||||
Categories can be shown as tabs (:ref:`settings categories_as_tabs`) in the
|
|
||||||
UI. A search in a tab (in the UI) will query all engines that are active in
|
|
||||||
this tab. In the preferences page (``/preferences``) -- under *engines* --
|
|
||||||
users can select what engine should be active when querying in this tab.
|
|
||||||
|
|
||||||
Alternatively, :ref:`\!bang <search-syntax>` can be used to search all engines
|
|
||||||
in a category, regardless of whether they are active or not, or whether they
|
|
||||||
are in a tab of the UI or not. For example, ``!dictionaries`` can be used to
|
|
||||||
query all search engines in that category (group).
|
|
||||||
|
|
||||||
``timeout`` : optional
|
|
||||||
Timeout of the search with the current search engine. Overwrites
|
|
||||||
``request_timeout`` from :ref:`settings outgoing`. **Be careful, it will
|
|
||||||
modify the global timeout of SearXNG.**
|
|
||||||
|
|
||||||
``api_key`` : optional
|
|
||||||
In a few cases, using an API needs the use of a secret key. How to obtain them
|
|
||||||
is described in the file.
|
|
||||||
|
|
||||||
``disabled`` : optional
|
|
||||||
To disable by default the engine, but not deleting it. It will allow the user
|
|
||||||
to manually activate it in the settings.
|
|
||||||
|
|
||||||
``inactive``: optional
|
|
||||||
Remove the engine from the settings (*disabled & removed*).
|
|
||||||
|
|
||||||
``language`` : optional
|
|
||||||
If you want to use another language for a specific engine, you can define it
|
|
||||||
by using the ISO code of language (and region), like ``fr``, ``en-US``,
|
|
||||||
``de-DE``.
|
|
||||||
|
|
||||||
``tokens`` : optional
|
|
||||||
A list of secret tokens to make this engine *private*, more details see
|
|
||||||
:ref:`private engines`.
|
|
||||||
|
|
||||||
``weight`` : default ``1``
|
|
||||||
Weighting of the results of this engine.
|
|
||||||
|
|
||||||
``display_error_messages`` : default ``true``
|
|
||||||
When an engine returns an error, the message is displayed on the user interface.
|
|
||||||
|
|
||||||
``network`` : optional
|
|
||||||
Use the network configuration from another engine.
|
|
||||||
In addition, there are two default networks:
|
|
||||||
|
|
||||||
- ``ipv4`` set ``local_addresses`` to ``0.0.0.0`` (use only IPv4 local addresses)
|
|
||||||
- ``ipv6`` set ``local_addresses`` to ``::`` (use only IPv6 local addresses)
|
|
||||||
|
|
||||||
``enable_http`` : optional
|
|
||||||
Enable HTTP for this engine (by default only HTTPS is enabled).
|
|
||||||
|
|
||||||
``retry_on_http_error`` : optional
|
|
||||||
Retry request on some HTTP status code.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
* ``true`` : on HTTP status code between 400 and 599.
|
|
||||||
* ``403`` : on HTTP status code 403.
|
|
||||||
* ``[403, 429]``: on HTTP status code 403 and 429.
|
|
||||||
|
|
||||||
``proxies`` :
|
|
||||||
Overwrites proxy settings from :ref:`settings outgoing`.
|
|
||||||
|
|
||||||
``using_tor_proxy`` :
|
|
||||||
Using tor proxy (``true``) or not (``false``) for this engine. The default is
|
|
||||||
taken from ``using_tor_proxy`` of the :ref:`settings outgoing`.
|
|
||||||
|
|
||||||
``max_keepalive_connection#s`` :
|
|
||||||
`Pool limit configuration`_, overwrites value ``pool_maxsize`` from
|
|
||||||
:ref:`settings outgoing` for this engine.
|
|
||||||
|
|
||||||
``max_connections`` :
|
|
||||||
`Pool limit configuration`_, overwrites value ``pool_connections`` from
|
|
||||||
:ref:`settings outgoing` for this engine.
|
|
||||||
|
|
||||||
``keepalive_expiry`` :
|
|
||||||
`Pool limit configuration`_, overwrites value ``keepalive_expiry`` from
|
|
||||||
:ref:`settings outgoing` for this engine.
|
|
||||||
|
|
||||||
.. note::
|
|
||||||
|
|
||||||
A few more options are possible, but they are pretty specific to some
|
|
||||||
engines, and so won't be described here.
|
|
||||||
|
|
||||||
|
|
||||||
Example: Multilingual Search
|
|
||||||
----------------------------
|
|
||||||
|
|
||||||
SearXNG does not support true multilingual search. You have to use the language
|
|
||||||
prefix in your search query when searching in a different language.
|
|
||||||
|
|
||||||
But there is a workaround: By adding a new search engine with a different
|
|
||||||
language, SearXNG will search in your default and other language.
|
|
||||||
|
|
||||||
Example configuration in settings.yml for a German and English speaker:
|
|
||||||
|
|
||||||
.. code-block:: yaml
|
|
||||||
|
|
||||||
search:
|
|
||||||
default_lang : "de"
|
|
||||||
...
|
|
||||||
|
|
||||||
engines:
|
|
||||||
- name : google english
|
|
||||||
engine : google
|
|
||||||
language : en
|
|
||||||
...
|
|
||||||
|
|
||||||
When searching, the default google engine will return German results and
|
|
||||||
"google english" will return English results.
|
|
||||||
|
|
||||||
|
|
||||||
.. _settings use_default_settings:
|
|
||||||
|
|
||||||
use_default_settings
|
|
||||||
====================
|
|
||||||
|
|
||||||
.. sidebar:: ``use_default_settings: true``
|
|
||||||
|
|
||||||
- :ref:`settings location`
|
|
||||||
- :ref:`use_default_settings.yml`
|
|
||||||
- :origin:`/etc/searxng/settings.yml <utils/templates/etc/searxng/settings.yml>`
|
|
||||||
|
|
||||||
The user defined ``settings.yml`` is loaded from the :ref:`settings location`
|
|
||||||
and can relied on the default configuration :origin:`searx/settings.yml` using:
|
|
||||||
|
|
||||||
``use_default_settings: true``
|
|
||||||
|
|
||||||
``server:``
|
|
||||||
In the following example, the actual settings are the default settings defined
|
|
||||||
in :origin:`searx/settings.yml` with the exception of the ``secret_key`` and
|
|
||||||
the ``bind_address``:
|
|
||||||
|
|
||||||
.. code-block:: yaml
|
|
||||||
|
|
||||||
use_default_settings: true
|
|
||||||
server:
|
|
||||||
secret_key: "ultrasecretkey" # change this!
|
|
||||||
bind_address: "0.0.0.0"
|
|
||||||
|
|
||||||
``engines:``
|
|
||||||
With ``use_default_settings: true``, each settings can be override in a
|
|
||||||
similar way, the ``engines`` section is merged according to the engine
|
|
||||||
``name``. In this example, SearXNG will load all the default engines, will
|
|
||||||
enable the ``bing`` engine and define a :ref:`token <private engines>` for
|
|
||||||
the arch linux engine:
|
|
||||||
|
|
||||||
.. code-block:: yaml
|
|
||||||
|
|
||||||
use_default_settings: true
|
|
||||||
server:
|
|
||||||
secret_key: "ultrasecretkey" # change this!
|
|
||||||
engines:
|
|
||||||
- name: arch linux wiki
|
|
||||||
tokens: ['$ecretValue']
|
|
||||||
- name: bing
|
|
||||||
disabled: false
|
|
||||||
|
|
||||||
|
|
||||||
``engines:`` / ``remove:``
|
|
||||||
It is possible to remove some engines from the default settings. The following
|
|
||||||
example is similar to the above one, but SearXNG doesn't load the the google
|
|
||||||
engine:
|
|
||||||
|
|
||||||
.. code-block:: yaml
|
|
||||||
|
|
||||||
use_default_settings:
|
|
||||||
engines:
|
|
||||||
remove:
|
|
||||||
- google
|
|
||||||
server:
|
|
||||||
secret_key: "ultrasecretkey" # change this!
|
|
||||||
engines:
|
|
||||||
- name: arch linux wiki
|
|
||||||
tokens: ['$ecretValue']
|
|
||||||
|
|
||||||
``engines:`` / ``keep_only:``
|
|
||||||
As an alternative, it is possible to specify the engines to keep. In the
|
|
||||||
following example, SearXNG has only two engines:
|
|
||||||
|
|
||||||
.. code-block:: yaml
|
|
||||||
|
|
||||||
use_default_settings:
|
|
||||||
engines:
|
|
||||||
keep_only:
|
|
||||||
- google
|
|
||||||
- duckduckgo
|
|
||||||
server:
|
|
||||||
secret_key: "ultrasecretkey" # change this!
|
|
||||||
engines:
|
|
||||||
- name: google
|
|
||||||
tokens: ['$ecretValue']
|
|
||||||
- name: duckduckgo
|
|
||||||
tokens: ['$ecretValue']

The initial ``settings.yml`` we be load from these locations:

1. the full path specified in the ``SEARXNG_SETTINGS_PATH`` environment variable.
|
||||||
|
2. ``/etc/searxng/settings.yml``
|
||||||
|
|
||||||
|
If these files don't exist (or are empty or can't be read), SearXNG uses the
|
||||||
|
:origin:`searx/settings.yml` file. Read :ref:`settings use_default_settings` to
|
||||||
|
see how you can simplify your *user defined* ``settings.yml``.

``engines:`` / ``remove:``
|
||||||
|
It is possible to remove some engines from the default settings. The following
|
||||||
|
example is similar to the above one, but SearXNG doesn't load the the google
|
||||||
|
engine:
|
||||||
|
|
||||||
|
.. code:: yaml
|
||||||
|
|
||||||
|
use_default_settings:
|
||||||
|
engines:
|
||||||
|
remove:
|
||||||
|
- google
|
||||||
|
server:
|
||||||
|
secret_key: "ultrasecretkey" # change this!
|
||||||
|
engines:
|
||||||
|
- name: arch linux wiki
|
||||||
|
tokens: ['$ecretValue']
|
||||||
|
|
||||||
|
``engines:`` / ``keep_only:``
|
||||||
|
As an alternative, it is possible to specify the engines to keep. In the
|
||||||
|
following example, SearXNG has only two engines:
|
||||||
|
|
||||||
|
.. code:: yaml
|
||||||
|
|
||||||
|
use_default_settings:
|
||||||
|

|
||||||
|
keep_only:
|
||||||
|
- google
|
||||||
|
- duckduckgo
|
||||||
|

|
||||||
|
secret_key: "ultrasecretkey" # change this!
|
||||||
|

|
||||||

``name`` :
|
||||||
|
Name that will be used across SearXNG to define this engine. In settings, on
|
||||||
|
the result page...
|
||||||
|
|
||||||
|
``engine`` :
|
||||||
|
Name of the python file used to handle requests and responses to and from this
|
||||||
|
search engine.
|
||||||
|
|
||||||
|
``shortcut`` :
|
||||||
|
Code used to execute bang requests (in this case using ``!bi``)
|
||||||
|
|
||||||
|
``base_url`` : optional
|
||||||
|
Part of the URL that should be stable across every request. Can be useful to
|
||||||
|
use multiple sites using only one engine, or updating the site URL without
|
||||||
|
touching at the code.
|
||||||
|
|
||||||
|
``send_accept_language_header`` :
|
||||||
|
Several engines that support languages (or regions) deal with the HTTP header
|
||||||
|
``Accept-Language`` to build a response that fits to the locale. When this
|
||||||
|
option is activated, the language (locale) that is selected by the user is used
|
||||||
|
to build and send a ``Accept-Language`` header in the request to the origin
|
||||||
|
search engine.
|
||||||
|
|
||||||
|
.. _engine categories:
|
||||||
|
|
||||||
|
``categories`` : optional
|
||||||
|
Specifies to which categories the engine should be added. Engines can be
|
||||||
|
assigned to multiple categories.
|
||||||
|
|
||||||
|
Categories can be shown as tabs (:ref:`settings categories_as_tabs`) in the
|
||||||
|
UI. A search in a tab (in the UI) will query all engines that are active in
|
||||||
|
this tab. In the preferences page (``/preferences``) -- under *engines* --
|
||||||
|
users can select what engine should be active when querying in this tab.
|
||||||
|
|
||||||
|
Alternatively, :ref:`\!bang <search-syntax>` can be used to search all engines
|
||||||
|
in a category, regardless of whether they are active or not, or whether they
|
||||||
|
are in a tab of the UI or not. For example, ``!dictionaries`` can be used to
|
||||||
|
query all search engines in that category (group).
|
||||||
|
|
||||||
|
``timeout`` : optional
|
||||||
|
Timeout of the search with the current search engine. Overwrites
|
||||||
|
``request_timeout`` from :ref:`settings outgoing`. **Be careful, it will
|
||||||
|
modify the global timeout of SearXNG.**
|
||||||
|
|
||||||
|
``api_key`` : optional
|
||||||
|
In a few cases, using an API needs the use of a secret key. How to obtain them
|
||||||
|
is described in the file.
|
||||||
|
|
||||||
|
``disabled`` : optional
|
||||||
|
To disable by default the engine, but not deleting it. It will allow the user
|
||||||
|
to manually activate it in the settings.
|
||||||
|
|
||||||
|
``inactive``: optional
|
||||||
|
Remove the engine from the settings (*disabled & removed*).
|
||||||
|
|
||||||
|
``language`` : optional
|
||||||
|
If you want to use another language for a specific engine, you can define it
|
||||||
|
by using the ISO code of language (and region), like ``fr``, ``en-US``,
|
||||||
|
``de-DE``.
|
||||||
|
|
||||||
|
``tokens`` : optional
|
||||||
|
A list of secret tokens to make this engine *private*, more details see
|
||||||
|
:ref:`private engines`.
|
||||||
|
|
||||||
|
``weight`` : default ``1``
|
||||||
|
Weighting of the results of this engine.
|
||||||
|
|
||||||
|
``display_error_messages`` : default ``true``
|
||||||
|
When an engine returns an error, the message is displayed on the user interface.
|
||||||
|
|
||||||
|
``network`` : optional
|
||||||
|
Use the network configuration from another engine.
|
||||||
|
In addition, there are two default networks:
|
||||||
|
|
||||||
|
- ``ipv4`` set ``local_addresses`` to ``0.0.0.0`` (use only IPv4 local addresses)
|
||||||
|
- ``ipv6`` set ``local_addresses`` to ``::`` (use only IPv6 local addresses)
|
||||||
|
|
||||||
|
``enable_http`` : optional
|
||||||
|
Enable HTTP for this engine (by default only HTTPS is enabled).
|
||||||
|
|
||||||
|
``retry_on_http_error`` : optional
|
||||||
|
Retry request on some HTTP status code.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
* ``true`` : on HTTP status code between 400 and 599.
|
||||||
|
* ``403`` : on HTTP status code 403.
|
||||||
|
* ``[403, 429]``: on HTTP status code 403 and 429.
|
||||||
|
|
||||||
|
``proxies`` :
|
||||||
|
Overwrites proxy settings from :ref:`settings outgoing`.
|
||||||
|
|
||||||
|
``using_tor_proxy`` :
|
||||||
|
Using tor proxy (``true``) or not (``false``) for this engine. The default is
|
||||||
|
taken from ``using_tor_proxy`` of the :ref:`settings outgoing`.
|
||||||
|
|
||||||
|
.. _Pool limit configuration: https://www.python-httpx.org/advanced/#pool-limit-configuration

Private Engines (``tokens``)
|
||||||
|
============================
|
||||||
|
|
||||||
|
Administrators might find themselves wanting to limit access to some of the
|
||||||
|
enabled engines on their instances. It might be because they do not want to
|
||||||
|
expose some private information through :ref:`offline engines`. Or they would
|
||||||
|
rather share engines only with their trusted friends or colleagues.
|
||||||
|
|
||||||
|
.. sidebar:: info
|
||||||
|
|
||||||
|
Initial sponsored by `Search and Discovery Fund
|
||||||
|
<https://nlnet.nl/discovery>`_ of `NLnet Foundation <https://nlnet.nl/>`_.
|
||||||
|
|
||||||
|
To solve this issue the concept of *private engines* exists.
|
||||||
|
|
||||||
|
A new option was added to engines named `tokens`. It expects a list of strings.
|
||||||
|
If the user making a request presents one of the tokens of an engine, they can
|
||||||
|
access information about the engine and make search requests.
|
||||||
|
|
||||||
|
Example configuration to restrict access to the Arch Linux Wiki engine:
|
||||||
|
|
||||||
|
.. code:: yaml
|
||||||
|
|
||||||
|
- name: arch linux wiki
|
||||||
|
engine: archlinux
|
||||||
|
shortcut: al
|
||||||
|
tokens: [ 'my-secret-token' ]
|
||||||
|
|
||||||
|
Unless a user has configured the right token, the engine is going to be hidden
|
||||||
|
from him/her. It is not going to be included in the list of engines on the
|
||||||
|
Preferences page and in the output of `/config` REST API call.
|
||||||
|
|
||||||
|
Tokens can be added to one's configuration on the Preferences page under "Engine
|
||||||
|
tokens". The input expects a comma separated list of strings.
|
||||||
|
|
||||||
|
The distribution of the tokens from the administrator to the users is not carved
|
||||||
|
in stone. As providing access to such engines implies that the admin knows and
|
||||||
|
trusts the user, we do not see necessary to come up with a strict process.
|
||||||
|
Instead, we would like to add guidelines to the documentation of the feature.
|
||||||
|
|
||||||
|
|
||||||
|
Example: Multilingual Search
|
||||||
|
============================
|
||||||
|
|
||||||
|
SearXNG does not support true multilingual search. You have to use the language
|
||||||
|
prefix in your search query when searching in a different language.
|
||||||
|
|
||||||
|
But there is a workaround: By adding a new search engine with a different
|
||||||
|
language, SearXNG will search in your default and other language.
|
||||||
|
|
||||||
|
Example configuration in settings.yml for a German and English speaker:
|
||||||
|
|
||||||
|
.. code-block:: yaml
|
||||||
|
|
||||||
|
search:
|
||||||
|
default_lang : "de"
|
||||||
|
...
|
||||||
|
|
||||||
|
engines:
|
||||||
|
- name : google english
|
||||||
|
engine : google
|
||||||
|
language : en
|
||||||
|
...
|
||||||
|
|
||||||
|
When searching, the default google engine will return German results and
|
||||||
|
"google english" will return English results.

|
||||||
|
* ``[ 192.168.0.1, 192.168.0.2 ]`` these two specific IP addresses
|
||||||
|
* ``fe80::60a2:1691:e5a2:ee1f``
|
||||||
|
* ``fe80::60a2:1691:e5a2:ee1f/126`` all IP addresses in this network.
|
||||||
|
* ``[ 192.168.0.1, fe80::/126 ]``
|
||||||
|
|
||||||
|
``retries`` :
|
||||||
|
Number of retry in case of an HTTP error. On each retry, SearXNG uses an

.. _Redis.from_url(url): https://redis-py.readthedocs.io/en/stable/connections.html#redis.client.Redis.from_url
|
||||||
|
|
||||||
|
A redis DB can be connected by an URL, in :py:obj:`searx.redisdb` you
|
||||||
|
will find a description to test your redis connection in SerXNG. When using
|
||||||
|
sockets, don't forget to check the access rights on the socket::
|
||||||
|
|
||||||
|
ls -la /usr/local/searxng-redis/run/redis.sock
|
||||||
|
srwxrwx--- 1 searxng-redis searxng-redis ... /usr/local/searxng-redis/run/redis.sock
|
||||||
|
|
||||||
|
In this example read/write access is given to the *searxng-redis* group. To get
|
||||||
|
access rights to redis instance (the socket), your SearXNG (or even your
|
||||||
|
developer) account needs to be added to the *searxng-redis* group.
|
||||||
|
|
||||||
|
``url`` : ``$SEARXNG_REDIS_URL``
|
||||||
|
URL to connect redis database, see `Redis.from_url(url)`_ & :ref:`redis db`::
|
||||||
|
|
||||||
|
redis://[[username]:[password]]@localhost:6379/0
|
||||||
|
rediss://[[username]:[password]]@localhost:6379/0
|
||||||
|
unix://[[username]:[password]]@/path/to/socket.sock?db=0
|
||||||
|
|
||||||
|
.. admonition:: Tip for developers
|
||||||
|
|
||||||
|
To set up a local redis instance, first set the socket path of the Redis DB
|
||||||
|
in your YAML setting:
|
||||||
|
|
||||||
|
.. code:: yaml
|
||||||
|
|
||||||
|
redis:
|
||||||
|
url: unix:///usr/local/searxng-redis/run/redis.sock?db=0
|
||||||
|
|
||||||
|
Then use the following commands to install the redis instance ::
|
||||||
|
|
||||||
|
$ ./manage redis.build
|
||||||
|
$ sudo -H ./manage redis.install
|
||||||
|
$ sudo -H ./manage redis.addgrp "${USER}"
|
||||||
|
# don't forget to logout & login to get member of group

Redis is an open source (BSD licensed), in-memory data structure (key value
|
|
||||||
based) store. Before configuring the ``redis_server`` engine, you must install
|
|
||||||
the dependency redis_.
|
|
||||||
|
|
||||||
Select a database to search in and set its index in the option ``db``. You can
|
|
||||||
either look for exact matches or use partial keywords to find what you are
|
|
||||||
looking for by configuring ``exact_match_only``. You find an example
|
|
||||||
configuration below:

MongoDB_ is a document based database program that handles JSON like data.
|
|
||||||
Before configuring the ``mongodb`` engine, you must install the dependency
|
|
||||||
redis_.
|
|
||||||
|
|
||||||
In order to query MongoDB_, you have to select a ``database`` and a
|
.. automodule:: searx.engines.mongodb
|
||||||
``collection``. Furthermore, you have to select a ``key`` that is going to be
|
:members:
|
||||||
searched. MongoDB_ also supports the option ``exact_match_only``, so configure
|
|
||||||
it as you wish. Below is an example configuration for using a MongoDB

collection:
|
|
||||||

Administrators might find themselves wanting to integrate locally running search
|
||||||
|
engines. The following ones are supported for now:
|
||||||
|
|
||||||
|
* `Elasticsearch`_
|
||||||
|
* `Meilisearch`_
|
||||||
|
* `Solr`_
|
||||||
|
|
||||||
|
Each search engine is powerful, capable of full-text search. All of the engines
|
||||||
|
above are added to ``settings.yml`` just commented out, as you have to
|
||||||
|
``base_url`` for all them.
|
||||||
|
|
||||||
|
Please note that if you are not using HTTPS to access these engines, you have to
|
||||||
|
enable HTTP requests by setting ``enable_http`` to ``True``.
|
||||||
|
|
||||||
|
Furthermore, if you do not want to expose these engines on a public instance,
|
||||||
|
you can still add them and limit the access by setting ``tokens`` as described
|
||||||
|
in section :ref:`private engines`.

SQLite is a small, fast and reliable SQL database engine. It does not require
|
|
||||||
any extra dependency. To demonstrate the power of database engines, here is a

more complex example which reads from a MediathekView_ (DE) movie database. For

- https://liste.mediathekview.de/filmliste-v2.db.bz2
|

||||||

and unpack into ``searx/data/filmliste-v2.db``. To search the database use e.g

.. attention::

|
|

|
When creating and enabling a ``command`` engine on a public instance, you
|
||||||
|
must be careful to avoid leaking private data.
|
||||||
|
|
||||||
|
The easiest solution is to limit the access by setting ``tokens`` as described
|
||||||
|
in section :ref:`private engines`. The engine base is flexible. Only your
|
||||||
|
imagination can limit the power of this engine (and maybe security concerns).
|

Configuration
|

=============
|
||||||
|
|

|
The following options are available:
|
||||||
|
|
||||||
|
``command``:
|
||||||
|
A comma separated list of the elements of the command. A special token
|
||||||
|
``{{QUERY}}`` tells where to put the search terms of the user. Example:
|
||||||
|
|
||||||
|
.. code:: yaml
|
||||||
|
|
||||||
|
['ls', '-l', '-h', '{{QUERY}}']
|
||||||
|

``delimiter``:
|
||||||
|
A mapping containing a delimiter ``char`` and the *titles* of each element in
|
||||||
|
``keys``.
|
||||||
|
|
||||||
|
``parse_regex``:
|
||||||
|
A dict containing the regular expressions for each result key.
|
||||||
|
|
||||||
|
``query_type``:
|
||||||
|
|
||||||
|
The expected type of user search terms. Possible values: ``path`` and
|
||||||
|
``enum``.
|
||||||
|
|
||||||
|
``path``:
|
||||||
|
Checks if the user provided path is inside the working directory. If not,
|
||||||
|
the query is not executed.
|
||||||
|
|
||||||
|
``enum``:
|
||||||
|
Is a list of allowed search terms. If the user submits something which is
|
||||||
|
not included in the list, the query returns an error.
|
||||||
|
|
||||||
|
``query_enum``:
|
||||||
|
A list containing allowed search terms if ``query_type`` is set to ``enum``.
|
||||||
|
|
||||||
|
``working_dir``:
|
||||||
|
The directory where the command has to be executed. Default: ``./``.
|
||||||
|
|
||||||
|
``result_separator``:
|
||||||
|
The character that separates results. Default: ``\\n``.

Elasticsearch_ supports numerous ways to query the data it is storing. At the
|
||||||
|
moment the engine supports the most popular search methods (``query_type``):
|
||||||
|
|
||||||
|
- ``match``,
|
||||||
|
- ``simple_query_string``,
|
||||||
|
- ``term`` and
|
||||||
|
- ``terms``.
|
||||||
|
|
||||||
|
If none of the methods fit your use case, you can select ``custom`` query type
|
||||||
|
and provide the JSON payload to submit to Elasticsearch in
|
||||||
|
``custom_query_json``.
|
||||||

MeiliSearch_ is aimed at individuals and small companies. It is designed for
|
||||||
|
small-scale (less than 10 million documents) data collections. E.g. it is great
|
||||||
|
for storing web pages you have visited and searching in the contents later.
|
||||||
|
|
||||||
|
The engine supports faceted search, so you can search in a subset of documents
|
||||||
|
of the collection. Furthermore, you can search in MeiliSearch_ instances that
|
||||||
|
require authentication by setting ``auth_token``.
