When using Luke to audit how ES tokenized and analyzed while indexing, the Lucene folder gets wiped when I open an index shard. 3 files are recreated (\_checksum-\*, segments.gen and segments\_1). Are the ES generated Lucene index compatible with Luke? Thanks, Remy ---

Found the thread "luke not recognizing index from ES git master"... Checksum file needs to be deleted. R.

Replied too fast. Deleting the checksum file does not solve this issue. Luke seems not to recognize the index format, saying: Index format: -11 (Lucene 1.3 or prior) which is obviously not the case. ---
