While searching 'All Computers' in the GSS Console (simple search) for computers with 'Application Name' > 'contains', and using a value matching the name of the application, some applications are returned with no computer results even though the application is installed on those machines.
GSS 3.3 RU11
The computer search pulls the application inventory from the eXpress DB table 'dbo.application'
The table 'dbo.application' lists the applications 'name' as MSI product GUID for applications installed using a .MSI (Microsoft Software Installer)
So, searching by the actual application name will not return results for software installed with the .MSI installer unless you search by MSI product GUID
This issue was resolve in the GSS 3.3 RU12 release.
Workaround: Searching by 'Application Description' for applications installed via a .MSI should return the desired results.
