Mark Harwood commented on LUCENE-9365:
--------------------------------------

I opened a [PR|https://github.com/apache/lucene-solr/pull/1493]

The fix required a Regex query rather than a wildcardquery because wildcard 
syntax doesn't support a variable number of changeable characters

> Fuzzy query has a false negative when prefix length == search term length

> 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.
