so you have lots of possible tags and many tags per event? then you need a btree with entry for each event for each tags, that is (<tag, date> -> event_id) btree. just as with SQL you'd need (tag, date, event_id) table. as elephant cannot sort tuples, you need to convert them to strings as i've noted before. _______________________________________________ elephant-devel site list elephant-devel@common-lisp.net http://common-lisp.net/mailman/listinfo/elephant-devel
