You can achieve almost the same result using Ferret's built-in
FuzzyQuery. It works even better for misspellings than phonetic
algorithms, and it's language-neutral.
Consider:
i = Ferret::I.new
i << "the quick brown fox"
i.search("quikc~").total_hits
=> 1
i.search("qwick~").total_hits
=> 1
Whereas metaphone yields:
Text::Metaphone.double_metaphone("quick")
=> ["KK", nil]
Text::Metaphone.double_metaphone("quikc")
=> ["KKK", nil]
Cheers,
Andy
