Hi, Is there a goal for lucene to always be able to read indexes written by older versions of Lucene? For instance, I noticed that I could read 2.0 and 1.9 indexes with a 2.1 Lucene jar. (I also noticed that if I add a document to one of those older indexes, then they'll be rewritten in 2.1 format.) Should/can we expect that all future versions of Lucene will be able to read older indexes?
The reason I ask: we have some 2.0 indexes written onto "Write once" media. We would like to be able to keep those indexes, and not have to convert them to a newer format. (We don't plan to ever have to write to those indexes again.) Thanks! Lucifer
