Displaying Top Two Categories in Search Results

Hey guys,

I have an auto parts website, and I have 3500+ products, and will have almost 10k when done.

Huge problem is, when a customer searches "07 mazda 6 exhaust" nothing will come up.. (I have yet to add a search categories mod).

However, I want to take steps, and still improve search results.

Suppose someone searches "hks exhaust" (product manufacturer and item, both are IN the title, so it will show).
I want the search results to display the top two categories alogn with the price, title, model number, etc.

How can I do this, or does anyone have a small script I can add in?

This would be of huge help, and I am willing to donate for a working fix.

Please let me know, any tips, idea.

Essentially, I want search results to show the first two categories. In my website's case:

Acura > Integra 94-01
or
Honda > Civic 01-05
or
Lexus > IS350 06-Up

etc etc.

Hope I'm making sense here..

Please let me know, i really appreciate it!
