I'm pretty sure you call IndexReader.terms(),
go thru the TermEnum,
and sort based on TermEnum.docFreq().
Will prob use a SortedMap (TreeMap) &
a custom Comparator. Actually maybe
you put each Term into a List
and call Collections.sort() on it.

There was a class in the test directory that efficiently computed this,
but I think Otis recently removed it.  Perhaps it should be revived and
go in the sandbox or something...

Yes, I was going to post it.
I kept a copy, of course :)  So I'll stick it in CVS somewhere soon.
