> When using FuzzyQuery the search string `bba` does not match doc value `bbab` with an edit distance of 1 and prefix length of 3.
> In FuzzyQuery an automaton is created for the "suffix" part of the search string which in this case is an empty string.
> In this scenario maybe the FuzzyQuery should rewrite to a WildcardQuery of the following form :
> {code:java}
>     searchString + "?" 
> {code}
> .. where there's an appropriate number of ? characters according to the edit distance.
