+Multilingual Search
+===================
+
+Searx 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, Searx will search in your default and other language.
+
+Example configuration in settings.yml for a German and English speaker:
+ .. code-block:: yaml
+
+    search:
+        language : "de"
+        ...
+
+    engines:
+      - name : google english
+        engine : google
+        language : english
+        ...
+
+When searching, the default google engine will return German results and "google english" will return English results.
