I too am experiencing this same issue and what you are saying to do no longer exists.  There is no option to go back to the classic search option.  I used to be able to search the information I had plugged into the invoice or purchase order, but that is no longer possible. We are an aviation business and often have to pull a search on a a tail number or serial number.  I have tried putting that info in the PO line, and while it comes up it is buried in 100+ other transactions that have absolutely nothing to do with what I am looking for. If I don't have a customer name I am s.o.l. (example: the plane was sold multiple time and this is the 3rd guy down the line looking for an authorization - he doesn't know who owned it back in 2004)
