+
+  NOTES
+    quick_prefix_select is made over the conditions on the whole key.
+    It defines a number of ranges of length x. 
+    However when jumping through the prefixes we use only the the first 
+    few most significant keyparts in the range key. However if there
+    are more keyparts to follow the ones we are using we must make the 
+    condition on the key inclusive (because x < "ab" means 
+    x[0] < 'a' OR (x[0] == 'a' AND x[1] < 'b').
+    To achive the above we must turn off the NEAR_MIN/NEAR_MAX
