 Selectors
 `````````
 
-A selector is responsible to score how well an object may be used with a
-given result set during publishing time selection. This enables the selection
-of the most appropriate views to a given result set.
+Selectors are scoring functions that are called by the view
+dispatcher to tell whenever a view can be applied to a given result
+set and request. Selector sets are the glue that tie views to the data
+model. Using them appropriately is an essential part of the
+construction of well behaved cubes.
 
-A selector is a method that computes a score. This score is used by
-`CubicWeb` engine to identify which view is the best to apply in the
-context. In the case, no score is higher than the others, then an
-exception is raised ``NoSelectableObject`` to let you know that the
-engine was not able to identify the view to apply. In such case
-you would need to review your design and make sure your views are
-properly defined.

 `CubicWeb` provides its own set of selectors that you can use and here
 is a description of some of the most common used:
 
-*yes_selector*
+*yes*
     This selector accepts everything which basically means to any result
     set.
 
-*norset_selector*
+*none_rset*
     This selector accepts no result set, so it can be applied to any
     object.
 
-*rset_selector*
-    This selector accepts result set, whatever the number of objects
+*rset*
+    This selector accepts any result set, whatever the number of objects
     in the result set.
 
-*anyrset_selector*
+*nonempty_rset*
     This selector accepts any non empty result set.
 
-*emptyrset_selector*
-    This selector accepts empty result set.
+*empty_rset*
+    This selector accepts empty (only) result set.
 
-*onelinerset_selector*
+*one_line_rset*
     This selector accepts result set with a single line of result.
 
-*twolinerset_selector*
+*two_lines_rset*
     This selector accepts result set with *at least* two lines of result.
 
-*anonymous_selector*
+*two_cols_rset*
+    This selector accepts result set with *at least* one line and two columns of result.
+
+*anonymous_user*
     This selector accepts if user is anonymous.
 
-*not_anonymous_selector*
-    This selector accepta if user is authenticated.
+*authencated_user*
+    This selector accepts if user is authenticated.
