Luke says my Lucene index directory is Invalid

Question

I'm trying to learn about Lucene, and hope to use Luke to investigate it. I tried building an index with the IndexFiles demo in Lucene 4.3, then tried viewing the index with the latest version of Luke, and I'm getting the message:

Invalid directory at the location, check console for more information. Last exception:
org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource: ChecksumIndexInput(MMapIndexInput(path="/home/lavin/sep20.index/segments_2"))): 1 (needs to be between 0 and 0)

Any ideas what's wrong and how to fix? Is my version of Lucene too new for Luke to decipher? Is there a way I can tell Lucene to write an older version of the index? Thanks in advance, -- Mark

Answer 1

you are probably using an older version of luke, the original maintainer no longer updates it to new versions of Lucene.

Get the latest from this guy. He keeps it up to date.
