Hi Vincent, Unfortunately, your assumption is incorrect, Lucene 9 is not able to search Lucene 6 indexes as Lucene only keeps read access to indexes created by the current (9) or previous major version (8). You will need to reindex your 6.x index with Lucene 8 or 9 (preferred) to be able to search it with Lucene 9.
