Hello,

What I can tell you is this shouldn't work, even with Lucene:

   @Field(store = Store.YES, analyzer = @Analyzer(definition = "phonetic" ))
   @Field(store = Store.YES, analyzer = @Analyzer(definition = "ngram" ))
   private String value;

You need to give a different name to each field:

   @Field(store = Store.YES, analyzer = @Analyzer(definition = "phonetic" ))
   @Field(name = "value_ngram" , store = Store.YES, analyzer = @Analyzer(definition = "ngram" ))
   private String value;

Now the fact that duplicate fields work (or at least seems to work) with Lucene is a problem... But adding an exception would break backward compatibility, so I'm inclined to leave it as is. Duplicate fields *are* forbidden in Hibernate Search 6 already.
