Another complication is determining whether deletions have changed. We don't have a per-segment version number. We could either add a version to the segment (perhaps even in the deletions file)
Deletions (.del) --> ByteCount,BitCount,Bits ByteSize,BitCount --> Uint32 Bits --> <Byte>ByteCount If ByteCount is a Uint32, it's high bit will never be 1, so we could add a flags field first that always had that bit set to be able to tell the difference between an old .del file and a new style one. The flags would also leave room for future expansion (different representations of a bitvector when the number of documents deleted is very small, etc).
