Detailed Description

DatabaseVersionError indicates that a database is in an unsupported format.

From time to time, new versions of Xapian will require the database format to be changed, to allow new information to be stored or new optimisations to be performed. Backwards compatibility will sometimes be maintained, so that new versions of Xapian can open old databases, but in some cases Xapian will be unable to open a database because it is in too old (or new) a format. This can be resolved either be upgrading or downgrading the version of Xapian in use, or by rebuilding the database from scratch with the current version of Xapian.
