Markus Heiser c80e82a855 [mod] DuckDuckGo: reversed engineered & upgrade to data_type: traits_v1
Partial reverse engineering of the DuckDuckGo (DDG) engines including a
improved language and region handling based on the enigne.traits_v1 data.

- DDG Lite
- DDG Instant Answer API
- DDG Images
- DDG Weather

docs/src/searx.engine.duckduckgo.rst:
  Online documentation of the DDG engines (make docs.live)

searx/data/engine_traits.json
  Add data type "traits_v1" generated by the fetch_traits() functions from:

  - "duckduckgo" (WEB),
  - "duckduckgo images" and
  - "duckduckgo weather"

  and remove data from obsolete data type "supported_languages".

searx/autocomplete.py:
  Reversed engineered Autocomplete from DDG.  Supports DDG's languages.

searx/engines/duckduckgo.py:
  - fetch_traits():  Fetch languages & regions from DDG.

  - get_ddg_lang(): Get DDG's language identifier from SearXNG's locale.  DDG
    defines its languages by region codes.  DDG-Lite does not offer a language
    selection to the user, only a region can be selected by the user.

  - Cache ``vqd`` value: The vqd value depends on the query string and is needed
    for the follow up pages or the images loaded by a XMLHttpRequest (DDG
    images).  The ``vqd`` value of a search term is stored for 10min in the
    redis DB.

  - DDG Lite engine: reversed engineered request method with improved Language
    and region support and better ``vqd`` handling.

searx/engines/duckduckgo_definitions.py: DDG Instant Answer API
  The *instant answers* API does not support languages, or at least we could not
  find out how language support should work.  It seems that most of the features
  are based on English terms.

searx/engines/duckduckgo_images.py: DDG Images
  Reversed engineered request method.  Improved language and region handling
  based on cookies and the enigne.traits_v1 data.  Response: add image format to
  the result list

searx/engines/duckduckgo_weather.py: DDG Weather
  Improved language and region handling based on cookies and the
  enigne.traits_v1 data.

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.
