   I installed the nugt artifact locally and the error seems to not occur as often as before, but I'm still able to reproduce it:
   
   ```System.IndexOutOfRangeException: Index was outside the bounds of the array.
      at Lucene.Net.Util.Automaton.UTF32ToUTF8.Convert(Automaton utf32)
      at Lucene.Net.Util.Automaton.CompiledAutomaton..ctor(Automaton automaton, Nullable`1 finite, Boolean simplify)

      at Lucene.Net.Search.IndexSearcher.CreateNormalizedWeight(Query query)
      at Lucene.Net.Search.IndexSearcher.Search(Query query, Int32 n, Sort sort)```
   
   With the added retry functionality, I wasn't able to produce 2 errors in a row using the same FuzzyQuery.
