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.
