Search engine

Ok, I know I know, your probabbly thinking, “Why not just use Google?”. I want my own search engine. Right now I have a massive server that has plenty of storage, MySQL database software, phpMyadmin, and I do not have an world wide web spider. So what I am asking for is a free World wide web Spider that goes out and simply grabs the, URL, and Site Description, and keywords. Then swiftly adds them to my MySQL database.

Thanks! Connor :D
