After discovering that the way Product Extra Fields was written prevents searching multiple fields for multiple search terms I wrote my own contribution which will do everything that Product Extra Fields does and more. You may find this new contribution at:

http://addons.oscommerce.com/info/6856

Included in the package is a file that converts all of your old Product Extra Fields into the new format used by my contribution so you can convert without losing the data you have already entered.

The attachment here is just a copy of the user guide for my contribution and is here only because a file is required to post this note.
