setIndexInterval

public WAH8DocIdSet.Builder setIndexInterval(int indexInterval)

Set the index interval. Smaller index intervals improve performance of DocIdSetIterator.advance(int) but make the DocIdSet larger. An index interval i makes the index add an overhead which is at most 4/i, but likely much less.The default index interval is 8, meaning the index has an overhead of at most 50%. To disable indexing, you can pass Integer.MAX_VALUE as an index interval.

public WAH8DocIdSet build()

Build a new WAH8DocIdSet.
