searching by tags....

Hey, this the first time I am actually working with "tags" but it seems quite popular and am adding it on a clients requests. By tags I mean something like wordpress' implementation of it, for example when an author writes an article on babies the tags might be baby,babies, new borns, cribs, nappies or a picture of a baby can have the tags baby,babies, new born, cute kid, nappies the tags are comma separated above of course. The way i am doing it right now is i have sayyyy an article or a pic saved in the db as article_or_pic_address text the_tags varchar(240) My question is, when someone clicks on any one of the tags, do i do a LIKE %search_term% search or...??? quite a few sites seem to have a very neat way of implementing this with (url rewriting?) something like http://sitename/blog/tags/tag-comes-here/ Any help in the form of advise, code or links would be appreciated. TIA. Cheers! Ryan ------ - The faulty interface lies between the chair and the keyboard. - Creativity is great, but plagiarism is faster! - Smile, everyone loves a moron. :-)
