Class Lucene42NormsFormat

Lucene 4.2 score normalization format.

NOTE: this uses the same format as Lucene42DocValuesFormat Numeric DocValues, but with different file extensions, and passing FASTEST for uncompressed encoding: trading off space for performance.

Files:

  • .nvd: DocValues data
  • .nvm: DocValues metadata
