Paul Elschot commented on LUCENE-1410:
--------------------------------------

bq. I'm trying now to get a rudimentary test working for TermQuery using pfor.

It should really make a difference for stop words and disjunction queries 
depending on DocIdSetIterator.next().

Conjunctions that depend on skipTo(docNum) will probably make it necessary to 
impose an upperbound the size of the compressed arrays. This upperbound could 
be the same as the skip distance in the index.

I'm wondering whether it would make sense to add skip info to the term 
positions of very large documents. Any ideas on that?
