setIndexInterval
public WAH8DocIdSet.Builder setIndexInterval(int indexInterval)
Set the index interval. Smaller index intervals improve performance ofDocIdSetIterator.advance(int)
but make theDocIdSet
larger. An index intervali
makes the index add an overhead which is at most4/i
, but likely much less.The default index interval is8
, meaning the index has an overhead of at most 50%. To disable indexing, you can passInteger.MAX_VALUE
as an index interval.
