what exactly does 'non-zero' mean?  Do you mean 'non-empty'?  If so, perhaps it
would be clearer to use 'non-empty'.

[Peter Kasting, 2012/12/20 19:09:29]

This was my same question.  See the earlier exchange with me.

[akalin, 2012/12/20 19:41:26]

I see.  I still think it should be clarified.  So non-zero means not equal to
the string "0"?  And empty string is a valid value distinct from it not being
present?

[Peter Kasting, 2012/12/20 19:43:17]

It's sounding from David's answer like we can scrap the nonzero and nonempty
parts and just use "present", which will make this moot.

Changed to "present in the query or ref".

Done.

+  // The parameter must be in the query if the search terms are in the query,
+  // and in the ref if the search terms are in the ref.

  private:
   // Private so we can enforce using the setters and thus enforce that these
   // fields are never empty.
