You might be better off starting with the Lucene CheckIndex program.
It walks all of the Lucene index data structures. I have done
forensics by fiddling with the CheckIndex code.

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.
I have

But if you're looking at the field length as the count of terms, that's

I have to ask,
Take a look at the scoring algorithm on the Wiki, it already takes
this into account, albeit modified by how many times the term
is mentioned in the field. So a field with 5 terms and one match
will score higher than one with 10 terms and one match. Where
it lands with 10 terms and 2 matches I

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

term length for
