-## Search
+### 7. Search
 
 Deck provides a global search either through the unified search in the Nextcloud header or with the inline search next to the board controls.
 This search allows advanced filtering of cards across all board of the logged in user.
 
 For example the search `project tag:ToDo assigned:alice assigned:bob` will return all cards where the card title or description contains project **and** the tag ToDo is set **and** the user alice is assigned **and** the user bob is assigned.
