Re: DatabaseModifiedError, how to handle it correctly when searching?

I think pretty much all Xapian functions which read the database
can throw DatabaseModifiedError.  I've been wrapping all
accesses with `eval {}' (Perl's standard exception trapping
mechanism).

I haven't used Xapian with other languages, but I expect the
bindings to work with the standard exception handling of
whatever language you're using (e.g begin/end for Ruby).
