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 AND, OR, and NOT. The queries are built and modified in the Query Builder. See the details in the Query Builder section.
Deskzilla is installed with several default sample queries, which can be removed if necessary.
To run the query, double-click the query name in the navigation pane or select it and click the Run Query button 
in the Application Toolbar.
After the query is ran once next to the query for the first time the number of bugs which this query selects is shown in blue next to the query 
. Queries which return empty results are grayed out 
.
To create a new query, do the following:
- On the navigation pane select the parent node for the query, right-click it and select New Query from the context menu or press F3 (⌘ + F3). The highest level parent is the connection.
- In the Create Query pop-up window specify the query expression. For the details see the Query Builder section.
- Deselect the Run Immediately check box if you do not want to run the query right after it is created.
- Click OK to finish the query creation.
To modify the query, do the following:
- On the navigation pane select the required query, right-click it and select Edit Query from the context menu or press Shift + F3 (⌘ + Shift + F3).
- In the Query Builder pop-up window modify the query expression. For the details see the Query Builder section.
- Deselect the Run Immediately check box if you do not want to run the query right after it is saved.
- Click OK to finish the query editing.
