Interesting, though I'm curious about whether this type of algorithm is state of the art for accuracy. At this time spell checkers are pretty much fast enough, but aren't always terribly good at suggesting replacements. I would imagine that systems based on n-grams are more effective.

it mentioned it's for search engines, in which case you may be checking against a massive wordlist taken from a search index, so accuracy isn't (quite) as important as speed.
