docs: // MinScore overrides the default value of 0 for the minimum similarity score.
  // Scores below this threshold are returned as 0 by Similarity() and Match().
  // The new value must be zero or positive. Note that a minimum greater than 1
  // can never be satisfied, resulting in a score of 0 for any pair of strings.
