"""Within this module we implement a *demo online engine*. Do not look to
|
|
close to the implementation, its just a simple example which queries `The Art
|
|
Institute of Chicago <https://www.artic.edu>`_
|
|
|
|
Configuration
|
|
=============
|
|
|
|
To get in use of this *demo* engine add the following entry to your engines
|
|
list in ``settings.yml``:
|
|
|
|
.. code:: yaml
|
|
|
|
- name: my online engine
|
|
engine: demo_online
|
|
shortcut: demo
|
|
disabled: false
