 The output of a [[filter|Filters]] step depends on its [[operator|Filter Operators]]:
 
-* Most operators perform <<.def relative>> to their input. They examine each input title in turn and filter out any that don't match. Such steps narrow down the output of a run.
+* Most operators derive their output from their input. For example, many of them output a subset of their input, and thus truly live up to the name of <<.word filters>>, narrowing down the overall output of the containing [[run|Filter Run]]. These operators are called <<.def "selection modifiers">>.
 
-* <<.def Absolute>> operators ignore their input and generate an independent output instead.
+* A few operators ignore their input and generate an independent output instead. These are called <<.def "selection constructors">>: they construct an entirely new [[selection|Title Selection]].
 
-A good example of an absolute operator is <<.olink title>>. The output of `[title[A]title[B]]` is just <<.tid B>>. But the <<.olink field>> operator is relative, so `[title[A]field:title[B]` outputs nothing at all.
