Hi. I've got a Lucene application that's been in use for about two years. Some users are using Lucene 1.2, some 1.3, and some are moving to 1.4. The indices seem to behave differently under each version. I'd like to add code to my application that checks the current user's index version against the version of Lucene that they are using, and automatically re-indexes their files if necessary. However, I can't figure out how to tell the version, from the index files.
The documentation on the file formats, at http://jakarta.apache.org/lucene/docs/fileformats.html, directs me to the "segments" file. However, when I look at a version 1.3 segments file, it seems to bear little relationship to the format described in fileformats.html. But the part of fileformats.html dealing with the segments file contains no "compatibility notes", so I assume it hasn't changed since 1.3. Even if it had, what's the idea of using -1 as the format number for 1.4? So, anyone know a way to tell the difference between the various versions of the index files? Crufty hacks welcome :-).
