Doesnt seem to be working for me. However! This is a great time to advertise that Alla has added era filtering for spells now! http://everquest.allakhazam.com/db/spelllist.html and select from the dropdown which era you would like to see what spells were available or came with that expansion. If anyone sees a spell that they believe isn't actually available or believes one is missing that should be included in an era feel free to post too and I'll get it corrected.
We're working on getting all those spells tagged since we recently got that option added to the spell search. Right now we're working on tagging 51 through 60 spells. We'll progressively work through all the levels eventually.
