Has anyone on here created a search engine in PHP?
Sure, of sorts, now and again, here and there, to some degree.

I am reasonably certain that if you Googled for:
"PHP web spider framework"
you would find several packages that would have at least 99% of what
you need... Because these simply have to exist out there.
From you description it seems like writing search engine (full text) is
simple task for three or four nights. It's not true.
Writing quality full text search engine is very complex task and you can
stuck at lots of problems. If you don't understand the theory of text
searching, you can finish it somehow, but it will not search the way
people are used to. The results will be wrong.
You think there have to be something written in PHP. There is not. Lots
of dead experiments - yes. Something good, working and in active
developement - no. There is even not much open source search engines
written in other languages. You just cannot stick to PHP - but it
doesn't matter in which language is the spider. You need only some
interface to the search part.
Here's my list:
mysql fulltext - toy for children
phpdig - lots of little problems here and there, unusable
htdig - dead, buggy
swish-e - dead?
swish++ - one man show?
aspseek - dead
mnogosearch - try it, it's not google, but usable, php interface
lucene - top quality, best query syntax
egothor - people says it's usable
did I forgot something good?
