Next, you had an index file Lucene.net in the Lucene.Net.Util.Version.LUCENE_29 version, ie the DLL is version 2.9. However a service ended indexing a new object in Lucene Lucene.Net.Util.Version.LUCENE_30 ie DLL is version 3.0.
With this my application that is fully developed in the Lucene.Net.Util.Version.LUCENE_29 version has stopped working, I get the following message:
Exception = Incompatible format version: 2 expected 1 or lower
Now I need to bring back the version Lucene.Net.Util.Version.LUCENE_29 to my index, but I can not find anything about it. I do not know reindex everything again which would be a lot of work because the index already has 2GB in size.
Does anyone know of any way to change the Lucene index version? I'm having this problem on account of only 1 doc inserted in the wrong version.
