<span class="sd">Brave regions</span>
<span class="sd">=============</span>
<span class="sd">Brave uses two-digit tags for the regions like ``ca`` while SearXNG deals with</span>
<span class="sd">locales. To get a mapping, all *officiat de-facto* languages of the Brave</span>
<span class="sd">region are mapped to regions in SearXNG (see :py:obj:`babel</span>
<span class="sd"><babel.languages.get_official_languages>`):</span>
<span class="sd">.. code:: python</span>
<span class="sd"> "regions": {</span>

<span class="sd"> "fr-CA": "ca",</span>
<span class="sd"> ..</span>
<span class="sd"> }</span>
<span class="sd">.. note::</span>
<span class="sd"> The language (aka region) support of Brave's index is limited to very basic</span>
<span class="sd"> languages. The search results for languages like Chinese or Arabic are of</span>
<span class="sd"> low quality.</span>
<span class="sd">.. _brave googles:</span>
<span class="sd">Brave Goggles</span>

<span class="sd">Goggles allow you to choose, alter, or extend the ranking of Brave Search</span>

<span class="sd">.. _brave languages:</span>
<span class="sd">Brave languages</span>
<span class="sd">===============</span>
<span class="sd">Brave's language support is limited to the UI (menus, area local notations,</span>
<span class="sd">etc). Brave's index only seems to support a locale, but it does not seem to</span>
<span class="sd">support any languages in its index. The choice of available languages is very</span>
<span class="sd">small (and its not clear to me where the difference in UI is when switching</span>
<span class="sd">from en-us to en-ca or en-gb).</span>
<span class="sd">In the :py:obj:`EngineTraits object <searx.enginelib.traits.EngineTraits>` the</span>
<span class="sd">UI languages are stored in a custom field named ``ui_lang``:</span>
