Searching a Table

I need to make a search engine for my site. Instead of making a table with all the words of my content of my reviews, I need to make it simple. How could you search a table of articles (let's say game_reviews) by comparing keywords the user types in, to the text of the article? All the tutorials I can find make a table with a list of words of every single keyword... Thanks, Stephen Craton http://www.melchior.us "Life is a gift from God.
