QueryParser can now handle minimumSimilarity parameter of FuzzyQuery; FuzzyQuery extended to allow for non-fuzzy prefixes.
This looks great!
It might also be good if one could set the non-fuzzy prefix length used by the QueryParser. As it stands, fuzzy queries with large indexes that use QueryParser are so slow they're unusable. But a default prefix of just a couple of characters would make a huge performance improvement.
Another idea might be to, rather than (or in addition to) limiting the number of expanded terms by similarity, to limit them by number. So one could keep, e.g., just the top-scoring 100 terms whose score is greater than 0.5, or somesuch. This way FuzzyQuery would never trigger BooleanQuery.TooManyClauses. What do you think?
Thanks for all the great code,
Doug
