Best way to code a search engine (across my database)?

1) build a logic that if the term isn't between " ", it searches for LIKE %$key% OR like %$key2% (so explode using the spaces) but if it's between " ", it leaves the space in...

2) you could run an ereg_replace on all your non standard letters, like é à etc. and replace them with e and a.
