TQL by default searches against the Entities index, but when performing searches against certain fields when using sub-selects, you will be searching against a different index.
On the Run History screens for Scripts, Script Assignments, Script Assignment Packages ( Execution Set Packages) and ( when using Duette) Automated Scripts and Automated Script Assignments, TQL defaults to search against the Run index.
From the global Search screen, can change to search against the Run Index by selecting Run in the Index drop down menu on the Search title bar.
