"""Implementation of the redis client (redis-py_).

.. _redis-py: https://github.com/redis/redis-py
|

This implementation uses the :ref:`settings redis` setup from ``settings.yml``.
|
|
A redis DB connect can be tested by::
|
|
|
|
>>> from searx.shared import redisdb
|
|
>>> redisdb.init()
|
|
True
|
|
>>> db = redisdb.client()
|
|
>>> db.set("foo", "bar")
|
|
True
|
|
>>> db.get("foo")
|
|
b'bar'
|
|
>>>
