I'm looking at trying to use both. My reason:
i = Ferret::I.new
i << "The quick brown fox"
i.search("qwik~").total_hits
=> 0
Where as double metaphoning "quick" or "qwik" both become "KK".
What I'm thinking might be a good solution is to index the word and it's
double-metaphone equivalent. Then search for exact hits against the metaphone
and fuzzy hits against the word field. Then sort based on score, with
hopefully exact matches being 100.
Still investigating the best solutions. Thanks for the ideas,
Curtis
