Robert,

I posted a comment just before your one (apparently in the same minute) - I made an additional point that TopTermsBoostOnlyBooleanQueryRewrite ignores the IDF undesirably - does that make the issue valid again?

> The FuzzyQuery often causes misspellings to be ranked higher than the exact match, which seems to be an undesirable property generally. 
> For example, in an index of surnames, if I search using a FuzzyQuery for "smith", the misspellings such as "smiith", or "smiht" would appear near the top of the search results ahead of documents that match "smith".
