Michael McCandless commented on LUCENE-9365:
--------------------------------------------

If that really fixes this corner case, then +1 to remove that minor 
optimization.

Actually, +1 to remove the optimization entirely, even if it doesn't fix this 
corner case -- it's optimizing a rare corner case anyways, which is a bad 
tradeoff (added code complexity for rare gains).

> 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.
