"""MongoDB_ is a document based database program that handles JSON like data.
|
|
Before configuring the ``mongodb`` engine, you must install the dependency
|
|
pymongo_.
|
|
|
|
Configuration
|
|
=============
|
|
|
|
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.
|
|
|
|
Example
|
|
=======
|
|
|
|
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
|
|
|
|
