keyword search syntax

I've got a field in my database that contains keywords about the particular record. I've got a form with a text entry field for visitors to enter keywords for which they would like to find records whose keyword field contains the words they entered. The submission form assigns the keywords entered to a variable which is passed via GET to the results page. What is the syntax for generating this query. I tried the following but it doesn't work... WHERE field CONTAINS $variableContainingKeywordEntry Can anyone help?
