Detailed Description

Within this module we implement a *demo offline engine*.  Do not look to
close to the implementation, its just a simple example.  To get in use of this
*demo* engine add the following entry to your engines list in ``settings.yml``:

.. code:: yaml

  - name: my offline engine
    engine: demo_offline
    shortcut: demo
    disabled: false

◆ init()

searx.engines.demo_offline.init ( engine_settings )

Initialization of the (offline) engine.  The origin of this demo engine is a
simple json string which is loaded in this example while the engine is
initialized.

◆ search()

EngineResults searx.engines.demo_offline.search	(		query,
			request_params )

Query (offline) engine and return results.  Assemble the list of results
from your local engine.  In this demo engine we ignore the 'query' term,
usual you would pass the 'query' term to your local engine to filter out the
results.
