Detailed Description

MySQL is said to be the most popular open source database.  Before enabling
MySQL engine, you must install the package ``mysql-connector-python``.

The authentication plugin is configurable by setting ``auth_plugin`` in the
attributes.  By default it is set to ``caching_sha2_password``.

Example
=======

This is an example configuration for querying a MySQL server:

.. code:: yaml

   - name: my_database
     engine: mysql_server
     database: my_database
     username: searxng
     password: password
     limit: 5
     query_str: 'SELECT * from my_table WHERE my_column=%(query)s'

Implementations
