Public Methods
virtual	~TextQueryRep ()
virtual void	startIteration ()=0
	This, along with hasMore(), nextTerm(), supports iteration over terms.
virtual bool	hasMore ()=0
virtual QueryTerm*	nextTerm ()=0
	Fetch the next term. A new instance is generated; the caller is responsible for deleting it!
virtual double	scoreConstant ()=0
	Any query-specific constant term in the scoring formula.
