Would IndexReader:
/**
* Reads version number from segments files. The version number is
* initialized with a timestamp and then increased by one for each
change of
* the index.
*
* @param directory where the index resides.
* @return version number.
* @throws CorruptIndexException if the index is corrupt
* @throws IOException if there is a low-level IO error
*/
public static long getCurrentVersion(Directory directory) throws
CorruptIndexException, IOException {
do what you are looking for? Also, why does it have to be in the
index if you are concerned about loading the whole IndexReader? That
is, if your application is versioning the application, why not just
store it in the same location or something like that?

e.g data
version etc?
Thanks
