Martin Fischer 61935c72ef [fix] remove broken ? search operator
The ? search operator has been broken for some time and
currently only raises the question why it's still there.

## Context ##

The query "Paris !images" searches for "Paris" in the "images" category.

Once upon a time Searx supported "Paris ?images" to search for "Paris"
in the currently enabled categories and the "images" category.

The feature makes sense ... the ? syntax does not.
We will hopefully introduce a +!images syntax in the future.

Fixes #702.

=============
Search syntax
=============
SearXNG allows you to modify the default categories, engines and search language
via the search query.
Prefix ``!``
to set Category/engine
Prefix: ``:``
to set language
Abbrevations of the engines and languages are also accepted. Engine/category
modifiers are chainable and inclusive (e.g. with :search:`!it !ddg !wp qwer
<?q=%21it%20%21ddg%20%21wp%20qwer>` search in IT category **and** duckduckgo
**and** wikipedia for ``qwer``).
See the :search:`/preferences page <preferences>` for the list of engines,
categories and languages.
Examples
========
Search in wikipedia for ``qwer``:
- :search:`!wp qwer <?q=%21wp%20qwer>` or
- :search:`!wikipedia qwer :search:<?q=%21wikipedia%20qwer>`
Image search:
- :search:`!images Cthulhu <?q=%21images%20Cthulhu>`
Custom language in wikipedia:
- :search:`:hu !wp hackerspace <?q=%3Ahu%20%21wp%20hackerspace>`
Multilingual Search
===================
SearXNG does not support true multilingual search.
You have to use the language prefix in your search query when searching in a different language.
But there is a workaround:
By adding a new search engine with a different language, SearXNG will search in your default and other language.
Example configuration in settings.yml for a German and English speaker:
.. code-block:: yaml
search:
language : "de"
...
engines:
- name : google english
engine : google
language : english
...
When searching, the default google engine will return German results and "google english" will return English results.
