 and click **Search or filter results...**. Merge requests can be filtered by author, assignee,
 milestone, and label.
 
+### Searching for specific terms
+
+You can filter issues and merge requests by specific terms included in titles or descriptions.
+
+* Syntax
+    * Searches look for all the words in a query, in any order. E.g.: searching
+      issues for `display bug` will return all issues matching both those words, in any order.
+    * To find the exact term, use double quotes: `"display bug"`
+* Limitation
+    * For performance reasons, terms shorter than 3 chars are ignored. E.g.: searching
+      issues for `included in titles` is same as `included titles`
