Queries are a convenient tool which allows users to create, save, and run bug filters, thus viewing the bugs, which meet the specified criteria - for example, critical bugs submitted today.Queries work as Boolean expressions and support three most common logic operators allow you to filter bugs by complex criteria, name and save these filters, and then apply them to different elements, such as other queries. Queries are built and modified in the Query Builder and consist of several conditions linked together by the common logic operators: AND, OR, and NOT.

The query name is automatically changed. All its parent queries are added as a prefix separated from each other with an asterisk (*). For example, "All Bugs*Reported by Me*Open".
