For this situation, searching the memo field isn't an option. (Many years of legacy data.) I note that you begin by saying, "From the invoice page....." So suppose I don't begin at the invoice page. Is this something that can be done by beginning somewhere else? I don't know where that "somewhere else" is because I don't know what I don't know. But perhaps within the Reports section from the main menu? There is an item near the bottom of the Reports menu called Custom Reports. Could what I need be done using the Custom Reports feature? 

And, by the way, when I referred to "search term" I wasn't talking about "payment terms." I meant "search term" in the sense of "data that a person is searching for."
