Comment(by OllyBetts):

 Since the index is apparently automatically rebuilt if it doesn't exist,
 the forward/backward compatibility could be solved by automatically
 deleting the Xapian index if you get a Xapian::DatabaseVersionError
 exception (which means "I don't understand this index version").

 If you want to recover from corruption of the Xapian index, doing the same
 for Xapian::DatabaseCorruptError would work, though it might be a good
 idea to report the issue somehow to avoid papering over genuine problems.

 As to which Xapian version to use, read the NEWS file to see the user-
 visible changes.  This also covers big internal changes which shouldn't be
 user-visible, but are potentially destabilising (which would be user-
 visible).

 There certainly have been a few bug fixes and several performance
 improvements since 1.0.2, but these may not be for cases which matter to
 you.
