how to do a search engine on my tables ?

[Anon]

Preaty much, I'd like to make a search engine for my tables usig bolean model.

so if someone search for:
+arg1 -arg3 +"arg4 arg2"

then I want to build a query:
SELECT * FROM database WHERE table LIKE '%$arg1%' AND NOT WHERE table LIKE '%$arg3%' AND WHERE table LIKE '%"arg4 arg2"%'

any help ?
Thanks
