The following are a few examples of simple filters:

Include only issues whose current state is Submitted
DefectState == "Submitted"
Retrieve only new issues submitted by user jhasler
status == "New"
submittedBy == "jhasler"
Exclude all records that were submitted by users oarmstrong or hrondo
Owner != "oarmstrong"
Owner != "hrondo"
Exclude all issues that are associated with ChildProject1 or ChildProject2
Project != "ChildProject1"
Project != "ChildProject2" 
Note: Rally only: The use of a filter is very helpful for specifying which Rally projects to exclude or include when Rally has nested projects.

The AccuSync filter editor is similar to the AccuWork Query Editor. See your AccuRev documentation for more information.
