That's traditionally been a troublesome query for Lucene indexes.
Luckily there's a recent Lucene feature called TrieRange [1,2] that
pretty much solves that issue and makes numeric range queries really
fast.

TrieRange hasn't yet been integrated with Jackrabbit, but if there's
demand it'll definitely be included in the Jackrabbit 2.x cycle.
Contributions are of course welcome. :-)
