Advanced Search Script

I need an advanced search engine script for my website. I have a quotation website similar to [login to view URL] using a mysql database with the following tables: "quotation" "author" "topic" I just want a really good search built for the site to function like the one on [login to view URL], an exact replica. I will give you access to the server and database. I will customize the design myself, I just need the script with instructions on how to install. For instance if you search "love" like so: [login to view URL] It displays: Quotes by: show all authors with "love" in their name Quotes about: shows all topics related to "love" Quotes with: shows keywords with "love" --- If you make a spelling error for instance searching "bemjamin" like so: [login to view URL] It returns results saying: Did you mean: Benjamin? --- I would like all of the features it uses.
