Ah, clever.  I was going to suggest adding another value to indicate
the presence or absence of these Xapian values, but I like your
solution better.  The only downside I can think of is that it might
not extend to other headers if we store more header values in the
database in the future.

I'd say this patch looks good other than coding style
- Tab indentation
- /* */ comments, starting with a capital letter
- Space between function name and open paren
- Space after comma in argument lists
- Spaces around assignment operator
