  Sets if the IndexWriter should pack newly written segments in a
  compound file. Default is true.
  
  Use false for batch indexing with very large ram buffer settings.
  
  Note: To control compound file usage during segment merges see
  SetNoCFSRatio() and SetMaxCFSSegmentSizeMB(). This setting only
  applies to newly created segment.
