Question

Ok, I attempted at making my own search function which doesnt work very well.

It consists of eliminating useless words such as “how” “you” “to” then using a premade Stemmer class that reduces words to their root so “Appointments” searches “appoint”

However in the end I’m really only searching keywords and the results are not very accurate.

Are there open source search engines that i can implement for free?

Answer 1

I’ve seen implementation of the Lucene Search engine in PHP using the Zend_Search_Lucene class, which obviously uses the Zend Framework library, check out a few links.
