I want to allow my users to do powerful searches but I don't want to give them access to typing in SQL directly into the search form. I therefore must create some sort of search query language grammar. This would have standard features like AND OR NOT Literal ("") and wildcards.

We currently use radio buttons for AND/OR on our search forms. Is allowing the user to type in these advanced queries instaed the best approach and how should I go about thinking about parsing them
