Search within a Search

We have created a search function that lists a persons name, contact information, and a product line that the particular person carries. Our search works great, however, we would like to know if when the search comes back, if it is possible to have the name or product line linked so that when you click on either one of them, they conduct another search. For example, if Bonny Jones carrries "ABC clothing" and you are able to click on "ABC clothing" you will find anyone else carrying "ABC clothing" Is this possible and if so, how would we go about that? We are novices and would greatly appreciate any assistance.
The website is: www.northstarfashion.com if you conduct a general search, you'll see what we are talking about.

Thank you very much for your help!
