Something like this:

    query = xapian.Query('xapian')
    range = xapian.Query(xapian.Query.OP_VALUE_RANGE, 0, '1', '4')
    query = xapian.Query(xapian.Query.OP_FILTER, query, range)

No, though there is at least now a warning in the documentation.
There's a preliminary patch in bugzilla, but the encoding to use isn't
finalised yet.
