How to use Quick Search with a UDtable

I have a related question. I have a quick search set up for a UD table. This isn’t in code. The quick search only allows to return one value, and the like is set up in one value, so I while I can make the search only list key1 and remove key2’s that I don’t want, the screen is opening up multiple records because Key1 is the same even though key2 and key3 are not. Is there a way to limit the returned records to only where key2 and key3 are blank? (I am storing history in the same table, but the historical data has values in key2 and key3 to denote them.)

Return SysRowID


thank you!
