  71 Hey, Austin.  This is a very nice patch.  Short and sweet, a really nice\r
  72 performance improvement, and a nice gentle fallback.\r
  73 \r
  74 I just rebuilt my database and I can definitely see the improvements.\r
  75 Search results are incredibly snappy, and the resultant database is only\r
  76 about 8% bigger.\r
  77 \r
  78 I fully endorse this being pushed.\r
  79 \r
