In Lucene every on bit represents a search hit. It is a bitmask which filters specific bits in the sequence so they can be counted individually. I hope my explanation is useful to you, if not please contact me again. The code calculates the number of bits in the bitarray that are turned on (1). In Lucene every on bit represents a search hit.

What does the bitssetArray256 represent? Hans Hi do mind explaining some more as what this code actually does?

What does the bitssetArray256 represent?
