We have exactly what you're looking for, but it is written in ASP.
It has the features you were asking such as plusses, minuses and phrase search. If you're interested in it, we are selling the script for USD60.00, but if you need it in PHP, we are sure it can be easily converted. Please contact us for more info.
Sincerely,
The ASPTrek Team
