When for example 2 out of 3 iterators/scorers are required, one can
skip 'last'

At LUCENE-365
One more thing I missed. I don't quite get your point about skip() vs
next().
With or queries, skipping does not help as much comparing to and queries.

Our very simple/naive testing methodology for OrDocIdSetIterator:
5 sub iterators, each subiterators just iterate from 0 to 1,000,000.
The test iterates the OrDocIdSetIterator until next() is false.
Do you want me to run the same test against DisjunctDisi?

Hi guys:
We have been building a suite of boolean operators DocIdSets (e.g.
AndDocIdSet/Iterator, OrDocIdSet/Iterator, NotDocIdSet/Iterator). We
compared our implementation on the OrDocIdSetIterator (based on
DisjunctionMaxScorer code) with some code tuning, and we see the performance
doubled
