      public long indexNumBytes
      Byte size of the index.

    • totalTermCount

    • totalTermBytes

      public long totalTermBytes
      Total number of bytes (sum of term lengths) across all terms in the field.

    • nonFloorBlockCount

      public int nonFloorBlockCount
      The number of normal (non-floor) blocks in the terms file.

    • floorBlockCount

      public int floorBlockCount
      The number of floor blocks (meta-blocks larger than the allowed maxItemsPerBlock) in the terms file.

    • floorSubBlockCount

      The number of sub-blocks within the floor blocks.

    • mixedBlockCount

      public int mixedBlockCount
      The number of "internal" blocks (that have both terms and sub-blocks).

    • termsOnlyBlockCount

      public int termsOnlyBlockCount
      The number of "leaf" blocks (blocks that have only terms).

    • subBlocksOnlyBlockCount

      public int subBlocksOnlyBlockCount
      The number of "internal" blocks that do not contain terms (have only sub-blocks).

    • totalBlockCount

      public int totalBlockCount
      Total number of blocks.

    • blockCountByPrefixLen

      public int[] blockCountByPrefixLen

      Total number of suffix bytes before compression.

    • totalBlockStatsBytes

      public long totalBlockStatsBytes

    • totalBlockOtherBytes

      public long totalBlockOtherBytes
      Total bytes stored by the PostingsReaderBase, plus the other few vInts stored in the frame.

    • segment

      public final String segment
