Lo peeps this is my first post to these forums, looks very active and I look forward to speeking with you guys. Anyway first question, i'm pretty new to PHP and MySQL ( about 3 weeks now ) but i'm learning fast, anyway I was studying the code of vBuleetin lite and I noticed a clause in one of the queries which I haven't come across yet. Can someone please tell me what the following means.

$query = "INDEX idxdisp(threadid,dateline)";

I'm v confused
