-   SearXNG supports {{engines | length}} search engines of which
-   {{enabled_engine_count}} are enabled by default.
-
-   Engines can be assigned to multiple :ref:`categories <engine categories>`.
-   The UI displays the tabs that are configured in :ref:`categories_as_tabs
-   <settings categories_as_tabs>`.  In addition to these UI categories (also
-   called *tabs*), engines can be queried by their name or the categories they
-   belong to, by using a :ref:`\!bing syntax <search-syntax>`.
