Detailed Description

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

Implementations
===============
