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
