Markus Heiser 1ec325adcc [mod] limiter -> botdetection: modularization and documentation
In order to be able to meet the outstanding requirements, the implementation is
modularized and supplemented with documentation.

This patch does not contain functional change, except it fixes issue #2455

----

Aktivate limiter in the settings.yml and simulate a bot request by::

    curl -H 'Accept-Language: de-DE,en-US;q=0.7,en;q=0.3' \
         -H 'Accept: text/html'
         -H 'User-Agent: xyz' \
         -H 'Accept-Encoding: gzip' \
         'http://127.0.0.1:8888/search?q=foo'

In the LOG:

    DEBUG   searx.botdetection.link_token : missing ping for this request: .....

Since ``BURST_MAX_SUSPICIOUS = 2`` you can repeat the query above two time
before you get a "Too Many Requests" response.

Differences to searx
====================

SearXNG is a fork of `searx`_, with notable changes:

.. _searx: https://github.com/searx/searx


User experience
---------------

- Reworked (and still simple) theme:

  * Usable on desktop, tablet and mobile.
  * Light and dark versions (available in the preferences).
  * Right-to-left language support.
  * `Screenshots <https://dev.searxng.org/screenshots.html>`_

- The translations are up to date, you can contribute on `Weblate`_
- The preferences page has been updated:

  * Browse which engines are reliable or not.
  * Engines are grouped inside each tab.
  * Each engine has a description.

- Thanks to the anonymous metrics, it is easier to report malfunctioning engines,
  so they get fixed quicker

  - `Turn off metrics on the server
    <https://docs.searxng.org/admin/engines/settings.html#general>`_ if you don't want them recorded.

- Administrators can `block and/or replace the URLs in the search results
  <https://github.com/searxng/searxng/blob/5c1c0817c3996c5670a545d05831d234d21e6217/searx/settings.yml#L191-L199>`_


Setup
-----

- No need for `Morty`_ to proxy images, even on a public instance.
- No need for `Filtron`_ to block bots, as there is now a built-in `limiter`_.
- A well maintained `Docker image`_, now also built for ARM64 and ARM/v7 architectures.
  (Alternatively there are up to date installation scripts.)

.. _Docker image: https://github.com/searxng/searxng-docker


Contributing
------------

- Readable debug log.
- Contributing is easier, thanks to the `Development Quickstart`_ guide.
- A lot of code cleanup and bugfixes.
- Up to date list dependencies.
