Simple MySQL Full-Text Search

Implement full-text search on 4 database fields in MySQL as per spec below. We are looking for a PHP implementation. MySQL's native boolean-full-text search would be fine, but we'll consider any reasonable alternatives. Bidders, please indicate relevant experience, and if you've done this before. Specifications -------------- 1. Generate search results from four MySQL fields (3 varchar and 1 text) based on words typed in a search box an a web page, and display them on that page. (We will provide the database with data.) 2. Results sorted by relevance, High>Low 3. Resuts sub-sorted by date (from the date field in MySQL) 4. Search-terms highlighted (in a yellow box controlled by a CSS rule) 5. When multiple search terms, "AND" is an default implied operator (changeable to "OR" in a config file) 6. When "AND", "OR, "NOT" terms are used in caps, they apply as such operators 7. Stopword list applies (from a config file) except inside a quoted expression which should be searched for an exact match as is. We will provide the list 8. Make "special" characters to be ignored in a search string so they don't break the search (look up from a config file. E.g. ",',?,! etc..) 9. Must work off mySQL FULLTEXT index or equivalent for high performance 10. Package code so search functionality/methods is in a class separate from UI functions (so it can be easily integrated into our app) 11. Desired: search results (relevancy score) weighted by field with weights applied/adjusted in a config file. (MySQL native text search may have some limitations here, but some reasonable work-arounds should be avaliable.)
