Hi!
I cannot open by lucene master my indexes created by lucene 8.5. I get an
error
Exception in thread "main" org.apache.lucene.index.CorruptIndexException:
codec mismatch: actual codec=Lucene84PostingsWriterDoc vs expected
codec=Lucene90PostingsWriterDoc

Files with UniformSplit has the same error. Are these codecs not backward
compatible? Is there any workaround?
Thank you!
