Hi Erick,

Are you sure you want to recompute the length when sorting?
It's the classic time/space tradeoff, but I'd suggest that when
your index is big enough to make taking up some more space
a problem, it's far too big to spend the cycles calculating each
term length for sorting purposes considering you may be
sorting all the terms in your index worst-case.
Good point, thank you for the clarification. I "thought" that Lucene
internally stores the field length (e.g., in order to compute the
relevance) and getting this information at query time requires only a
simple lookup.

But you could consider payloads for storing the length, although
that would still be redundant...

Hi folks,
is it possible to sort by field length without having to (redundantly) save
the length information in a seperate index field? At first, I thought to
accomplish this using a function query, but I couldn't find an appropriate
one.
Thanks in advance,
Sascha
