+                identification number (ID), which can be used to delete the
+                match using |matchdelete()|.
+
+                The optional {priority} argument assigns a priority to the
+                match.  A match with a high priority will have its
+                highlighting overrule that of a match with a lower priority.
+                A priority is specified as an integer (negative numbers are no
+                exception).  If the {priority} argument is not specified, the
+                default priority is 10.  The priority of 'hlsearch' is zero,
+                hence all matches with a priority greater than zero will
+                overrule it.  Syntax highlighting (see 'syntax') is a separate
+                mechanism, and regardless of the chosen priority a match will
+                always overrule syntax highlighting.
+
+                The optional {id} argument allows the request for a specific
+                match ID.  If a specified ID is already taken, an error
+                message will appear and the match will not be added.  An ID
+                is specified as a positive integer (zero excluded).  IDs 1, 2
+                and 3 are reserved for |:match|, |:2match| and |:3match|,
+                respectively.  If the {id} argument is not specified,
