NoSQL databases

- `NoSQL databases <https://en.wikipedia.org/wiki/NoSQL>`_
|
|
- `redis.io <https://redis.io/>`_
|
|
- `MongoDB <https://www.mongodb.com>`_
|
|
|
|
The following `NoSQL databases`_ are supported:
|
|
|
|
- :ref:`engine redis_server`
|
|
- :ref:`engine mongodb`
|
|
|
|
All of the engines above are just commented out in the :origin:`settings.yml
|
|
<searx/settings.yml>`, as you have to set various options and install
|
|
dependencies before using them.
|
|
|
|
By default, the engines use the ``key-value`` template for displaying results /
|
|
see :origin:`oscar <searx/templates/oscar/result_templates/key-value.html>` &
|
|
:origin:`simple <searx/templates/simple/result_templates/key-value.html>`
|
|
themes. If you are not satisfied with the original result layout, you can use
|
|
your own template, set ``result_template`` attribute to ``{template_name}`` and
|
|
place the templates at::
|
|
|
|
searx/templates/{theme_name}/result_templates/{template_name}
|
|
|
|
Futhermore, if you do not wish 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`.
|
|
|
|
|

|
`NoSQL databases`_ are used for storing arbitrary data without first defining
|
|
their structure.

Extra Dependencies
|
|
------------------
|
|
|
|
For using :ref:`engine redis_server` or :ref:`engine mongodb` you need to
|
|
install additional packages in Python's Virtual Environment of your SearXNG
|
|
instance. To switch into the environment (:ref:`searx-src`) you can use
|
|
:ref:`searx.sh`::
|
|
|
|
$ sudo utils/searx.sh shell
|
|
(searx-pyenv)$ pip install ...
|
|
|
|
|
|
.. _engine redis_server:
|
|
|
|
Redis Server
|
|
------------
|
|
|
|
.. _redis: https://github.com/andymccurdy/redis-py#installation
|
|
|
|
.. sidebar:: info
|
|
|
|
- ``pip install`` redis_
|
|
- redis.io_
|
|
- :origin:`redis_server.py <searx/engines/redis_server.py>`
|
|
|
|
|
|
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:
|
|
|
|
.. code:: yaml
|
|
|
|
# Required dependency: redis
|
|
|
|
- name: myredis
|
|
shortcut : rds
|
|
engine: redis_server
|
|
exact_match_only: false
|
|
host: '127.0.0.1'
|
|
port: 6379
|
|
enable_http: true
|
|
password: ''
|
|
db: 0
|
|
|
|
.. _engine mongodb:
|
|
|
|
MongoDB
|
|
-------
|
|
|
|
.. _pymongo: https://github.com/mongodb/mongo-python-driver#installation
|
|
|
|
.. sidebar:: info
|
|
|
|
- ``pip install`` pymongo_
|
|
- MongoDB_
|
|
- :origin:`mongodb.py <searx/engines/mongodb.py>`
|
|
|
|
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
|
|
``collection``. Furthermore, you have to select a ``key`` that is going to be
|
|
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:
|
|
|
|
.. code:: yaml
|
|
|
|
# MongoDB engine
|
|
# Required dependency: pymongo
|
|
|
|
- name: mymongo
|
|
engine: mongodb
|
|
shortcut: md
|
|
exact_match_only: false
|
|
host: '127.0.0.1'
|
|
port: 27017
|
|
enable_http: true
|
|
results_per_page: 20
|
|
database: 'business'
|
|
collection: 'reviews' # name of the db collection
|
|
key: 'name' # key in the collection to search for
|
