lucene version?

[Akanksha Baid <ba...@cs.wisc.edu>]

Is there a way to test as to which version of Lucene was used to build 
an index?

I don't think this is stored in the index.

I think the closest you can get is the "format" of the segments_N file
which changes every time the index file format changes.  That at least
lets you narrow it down possibly to a single release if the file
format is changing frequently (eg it has in the past 2 releases).

There's no public API to read the format.  You could instead make your
own class, in package org.apache.lucene.index, that implements a
method similar to how the SegmentInfos.readCurrentVersion(...) method
is implemented, but just returns the format instead.
