Is it possible to create a search within a previous set of results in the Code Referenvce tool?

Alternatively, I think you can use regular expressions, but I'm weak on them.

I'd like to find all the forms that both: use a specific table.

use taxunits in 0 

and make reference to a particular field : "due_date"

I have tons of forms that use that table, but have nothing to do with that date field, and I am looking for those specific ones to make maintenance changes to.
