 Current `swarm` supports affinity/constraint operators as the following: `==` and `!=`.
 
 For example,
-* `constraint:name==node1` will match nodes named with `node1`.
-* `constraint:name!=node1` will match all nodes, except `node1`.
+* `constraint:node==node1` will match node `node1`.
+* `constraint:node!=node1` will match all nodes, except `node1`.

-* `constraint:name==/node[12]/` will match nodes named `node1` and `node2`.
-* `constraint:name==/node\d/` will match all nodes named with `node` + 1 digit.

-* `constraint:name!=/foo\[bar\]/` will match all nodes, except those with name `foo[bar]`. You can see the use of escape characters here.
-* `constraint:name==/(?i)node1/` will match all nodes named with `node1` case-insensitive. So 'NoDe1' or 'NODE1' will also matched.
