Advanced Search Criteria Filters
You can set up advanced filters for both advanced and saved searches. Select filter fields and set their values on the Standard and Summary sublists located on the Criteria subtab.

A standard search filter finds results based on each record's value for a field. You can set up expressions for standard filters by checking the Use Expressions box.
If you add a field you don't have permission for, you'll see this message: “Your formula contains a reference to a field for which you do not have a permission.”
A summary search filter finds results based on calculated summary values for a group of records. You can only use this if you've set a summary type for a field on the Results tab.
If you set up more than one date filter, the one with the most recent date is used to calculate exchange rates, no matter what order you list them in.
