Search more than just Model & Description

I have searched the forum for 2-days, was hoping I didn't have to bother anyone but here goes.

First things first - My search & advanced search functions normal.

I have additional "Product Identifiers" if you will that I would like visitors to my site to be able to search by.

Instead of just searching by Model, is there a way they can search by the products SKU, UPC or ASIN also.

Any input would be greatly appreciated.
Thanks,
Ray

I don't know exactly how I did it but I did. The results are the same when I look up the products (Model, UPC, SKU, ASIN, Name, or part of the description)

I have created an issue with the search_results page tho - the Price Block for that product appears 3 times.

Any suggestions?

Thanks,
Ray

I fixed it. You can click here to see final results.

Manufacturer: Bello
Manufacturer Part Number: 657 88260
Manufacturer UPC: 748249072012
Products Catalog SKU: Y67676
Amazon ASIN: B001UNZ34E

You will see that you can search any of the following & get the same product now as to only being able to search (Manufacturer: & Manufacturer Part Number: *Model*) before.
