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.

"""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_.
|
|
|
|
Configuration
|
|
=============
|
|
|
|
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``.
|
|
|
|
Example
|
|
=======
|
|
|
|
Below is an example configuration:
|
|
|
|
.. 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
