I still don't have an answer. But I think I can ask the question more succinctly. 

Is it possible to search the description field of all invoices in a specific time period for a particular search term, and create a report of the results that includes, at the very least, the invoice number and the total amount of each invoice? 

If QB, out of the box, can't do this, fine. End of story. If it's possible but you don't provide step-by-step instructions as to how to do it in this forum, no problem. But then who do I contact for assistance? Is this something I need to contact a QB Expert to explain?
