+# Filters
+
+Filters are used to narrow down the search results.
+
+## Apply filters
+
+There are two ways to apply filters:
+
+1. Tap the <span class="material-symbols-rounded">filter_alt</span> icon in the search bar to open
+   the filter menu.
+2. Use the filter bar that is displayed above the keyboard when it is open.
+
+Filters are reset when the search bar is cleared.
+
+## Available filters
+
+- **Online results:** Allows the launcher to search online services like Wikipedia. This filter is
+  disabled by default, to protect your privacy.
+- **Type filters:**: Filter by result type (e.g., apps, contacts, files, places …). Neither of these
+  filters imply an online search. You need to enable the online results filter as well if
+  you want to search Wikipedia, for example.
+- **Hidden results**: Show search results that were hidden by the user.
+
+## Customization
+
+You can customize which filters are pre-selected by default in Settings > Search > Default filter.
+
+You can customize the items and order of the filters in the filter bar in Settings > Search >
+Customize filter bar.

+# Online Results
+
+Kvaesitso integrates with several online services, for example Wikipedia and OpenStreetMap.
+Additional online services can be integrated via plugins.
+
+In order to protect your privacy and to avoid unnecessary network traffic, online results are
+disabled by default.
+
+To enable online results, you need to enable the "Online results" filter.
+You can customize the default filter to always include online results, but keep in mind that this
+may have an impact on your privacy, since *all* search queries are sent to external services then.
+See [Filters](filters) for more information.
