> 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".
