* LUCENE-9365: FuzzyQuery was missing matches when prefix length was equal to
the term length
(Mark Harwood, Mike Drob)
+* LUCENE-9617: Reset lowestUnassignedFieldNumber on FieldNumbers.clear(), to
avoid leaking
Review comment:
How about something like this?:
```
Fix FieldInfos.clear() to reset its internal next field number state back to
0, which was otherwise causing a slow memory leak for applications relying on
IndexWriter.deleteAll.
```
