Constrained Quick Find

I don't know if this is possible but I was wondering if anyone has been able to figure out how to do a Constrain Quick find. I have some records that are related to a group of users and the rest that are not. When I perform any kind of search script, I put a set field that adds the restrain to it. Since a standard perform search function in a script has to have all fields return records, it works fine. But I have noticed that the quick find function goes across all records in the table. I tried to perform a regular find with the set requirements for the user then the quick find but that still jumps out. I had also moved the quick find to the top of the script then performed a constrain find but since the constrain find is only 1 item, it will always result in a found count greater than 0.

Does anyone have any ideas on a work around? I really need to have a single field that searches broadly through out the records but within a restrained set of records.
