So i've been recommended Zend search lucene php for search functionality, but is it better than mySql full text?

i've playing around with mysql's full text search and I'm not sure if it is the best.

let's say I search for "how do I book an appointment?" it will give me the correct results from the database, so "how can I book appointments?" I think it is because "book" is an开发者_StackOverflow中文版 uncommon word.

What if the user searches "how can I schedule an appointment?" I find it will not retrieve any records. I think it is because there are so many records with appointment in it.

So am I to understand a user can only get information on how to book an appointment if they use "book" in their question?

Lastly, should I be cleaning out words like "how","I" etc... in a mysql full text search? Should I be Stemming words as well?
