Just went through this myself. If you set *ref* as the query entity, you'll find your queries lose their complexity.
Ref.comment contains blah.
Ref.param = A
Etc. Etc.
If it works, thanks to David LeBer for the idea!

The user interface is as such that there is a list of all possible param assignments with a text field each. The user may now want to find all edocs that have a particular assignment to one or more params and the comment field on the ref-object contains "xyz". I have to build a query that may look something like

Oh, and the user might want to specify other qualifying values for the edocs he/she is looking for.
