PHP Make the search on our website work with 3 words

The search on our website mainly only works with a one word search. We would like it to work with 1, 2, and 3 words. These words may or may not be located right next to each other in the title or description of the item on our website. If you need more detail please email me at the email address on our website or through this website if that can be done. We have never used rentacoder before so not sure how all this works but I will learn. We have many projects, this is the smallest one. We will post more after we see how this one goes. The temporary search is on our slingshot page that is . . . . . <[login to view URL]> The seach as of right now, looks through a database on our website to get results. We are open to other methods if the coder has better ideas.
