+
+* **Apply structured filters:** Next to the search field, click the **Add filter** image:images/icons/addFilter.svg[Add filter icon] icon to add a custom filter. Notice that you can use `OR` and `AND` to combine filters. The structured filter can be disabled, inverted, or pinned across all apps.
+* **Enter a semi-structured search:** In the search field, start typing a field name to get suggestions for field names and operators that you can use to build a structured query. The semi-structured search will filter SLOs for matches, and only return matching SLOs.
+* Use the **Status** and **Tags** menus to include or exclude SLOs from the view based on the status or defined tags.
+
+There are also options to sort and group the SLOs displayed in the overview:

+* Click icons to switch between a card view (image:images/icons/apps.svg[Card view icon]), list view (image:images/icons/list.svg[List view icon]), or compact view (image:images/icons/tableDensityCompact.svg[Compact view icon]).
