Unless there is something I’m missing in regards to steps, I think we should submit this to the idea bank as I’d love to be able filter by GUID. The query tool allows you to bring over the GUID field as a filter, but doesn’t allow you to use it. Instead it takes the search to the Constituent Search screen where the Last/Org/Group name field is populated with the GUID I used in my filter. This happens in versions 2.5 and 2.91 and happens regardless of the type of GUID you are using (Constituent, Revenue, Funraising Purpose, etc.) – takes you to the standard search screen for that type of query.
