+Example: 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:
+        default_lang : "de"
+        ...
+
+    engines:
+      - name : google english
+        engine : google
+        language : en
+        ...
+
+When searching, the default google engine will return German results and
+"google english" will return English results.
