-          Sometimes, a query needs to compare a field containing
-          a user's ID (such as ReportedBy) with 
-          a user's ID (such as the user running the query or the user
-          to whom each bug is assigned). When the operator is either

+          Sometimes, a query needs to compare a user-related field
+          (such as ReportedBy) with a role-specific user (such as the
+          user running the query or the user to whom each bug is assigned).
+          When the operator is either "equals" or "notequals", the value
+          can be "%reporter%", "%assignee%", "%qacontact%", or "%user%".
+          The user pronoun
           refers to the user who is executing the query or, in the case
           of whining reports, the user who will be the recipient
           of the report. The reporter, assignee, and qacontact
           pronouns refer to the corresponding fields in the bug.

+          Boolean charts also let you type a group name in any user-related
+          field if the operator is either "equals", "notequals" or "anyexact".
+          This will let you query for any member belonging (or not) to the
+          specified group. The group name must be entered following the
+          "%group.foo%" syntax, where "foo" is the group name.
+          So if you are looking for bugs reported by any user being in the
+          "editbugs" group, then you can type "%group.editbugs%".
