  On the second series:

      test matched 19 times and opt1 was better
      start matched 1 time and none was better
      description matched 1 time and opt1 was better

  I can redo some tests today with more words, just to compare opt1
  and opt2 with different number of matches. Just let me know Chris.

  These are the average ft_snippets' contributions in percent of the
  total exec time:

      opt1-test 0.29
      opt1-start 0.76
      opt1-description 0.79
      
      opt2-test 0.31
      opt2-start 0.85
      opt2-description 0.82
