+PROX is a special boolean proximity operator “allowing for the relative locations of the terms to be used in order to determine the resulting set of records”. It is also the only Boolean operator to take (Boolean) modifiers:
+
+{{{
+PROX /unit = {unit}
+  /distance {comparison_operator} {number}
+  /ordered|unordered

+Examples for PROX:

+cat prox/unit=paragraph hat
