(11:17:04) Knuth Anders Hatlen: perhaps we should have an index format version and throw a more meaningful exception on startup: "Index is stored in an old format. Please recreate it from scratch."

(11:18:10) Taz: lucene version however might be different from version of what we store in it (11:19:00) Taz: I will file a bug on this, hmm ? (11:19:13) Knuth Anders Hatlen: Please do so! (11:19:57) Knuth Anders Hatlen: and yes, I think the Lucene index version is another issue (which lucence hopefully already handles for us)

I saw some kind of similar message in the indexer, isn’t this already implemented?

There is IndexVersion class however it is not used automatically.
