 I've been able to use Xapian's existing ValueRangeParser class to
 support date ranges similar to:

         20100101..20100131

 but what I'd really like instead is something like:

         date:"January 2010"

 or:

         date:"this month"

 Using a prefix like this matches the way the rest of my search strings
 are constructed, and as can be seen in the examples above, I want to
 support specifications of a range that don't have anything like the
 ".." syntax in them.

 Obviously, I'll be happy to do my own parsing of strings like "January
 2010" and "this month"---I just need a mechanism to hook my custom
 function to a prefixed chunk of query text.

 Olly suggested maybe the interface could be as general as my function
 just returning a query object. That would be a fairly powerful
 interface for doing all kinds of interesting things.
