null
, if this DocIdSet
does not support random access.
In contrast to DocIdSet.iterator()
, a return value of null
does not imply that no documents match the filter!
The default implementation does not provide random access, so you
only need to implement this method if your DocIdSet can
guarantee random access to every docid in O(1) time without
external disk access (as Bits
interface cannot throw
IOException
). This is generally true for bit sets
like FixedBitSet
, which return
itself if they are used as DocIdSet

This implementation can return null
