183066 Boolean Full Text Searching

I am currently utilizing an eCommerce script (PHP / MySQL Based). The search functionality of the script is extremely poor, thus time to remake. I need a script created which will allow for the following: 1. Search item title only 2. Search item description only 3. If neither of the above are checked, default is to search both. Search should allow for boolean. Example: "keyword here" with the quotes will do an -exact- earch for that phrase. "keyword AND here" will search for items with both of the words. "keyword OR here" will search for items with either word. Results should be returned in order of relevance. Pagination should be used, displaying 20 results per page. Full text searching seems faster to me, am open to suggestions. Terms: If you are selected as the winning bidder, you will be required to start on this job immediately.
