Opencart search engine problem

Hello, I'm new to opencart. I tried the search engine but i found that it displays the products only if all the search keywords are matched. I want to make it such a way that it should display the products even if 1 keyword is matched.

Smart Search can do this. It also has misspelling support and a bunch of other features to make the search more accurate. Feel free to take a look at the screenshots and demo site, and if you're interested let me know at www.getclearthinking.com/contact if you have any further questions.
