I think I figured out the problem after much digging and searching:


I do have a followup question...

In our search application, the Search::Xapian::QueryParser object is 
persistent.  Is there any kind of negative effect of having a value 
range processor set in the parser object when it isn't actually needed?

Most of our search requests will not be utilizing the date range option, 
so I'm somewhat concerned about using an option that isn't necessary 
most of the time.
