If you're using MySql then you could set the storage engine to MyIsam and use the fulltextsearch capability. See the MySql docs for more info.

He selects a keyword from the dropdown ?
Well, then, you can simply use, $query="select * from table where col like '%$value%'"; $value is the selected value of the dropdown.
