 * Refinements to random query generator:
-	* Fix to handle new, structured, relation representation
 	* Generate relation modifiers
 	* Proximity support
+	* Don't always generate qualifier/relation for terms
 	* Better selection of qualifier (configurable?)
 	* Better selection of terms (from a dictionary file?)
 	* Introduce wildcard characters into generated terms
