+.Ss USING MULTIPLE SELECTORS
+Multiple selectors in a single entry act as a union of match conditions.
+Each
+.Em facility.level
+pair is evaluated independently, and any message that matches
+any one of the selectors will be handled by the corresponding action.
+.Pp
+Consider the following combination of selectors:
+.Bd -literal -width offset
+mail.crit,*.err
+.Ed
+.Pp
+The combination of these selectors will select:

+.Bl -tag -width offset

+All messages from the mail facility at level crit or higher
+(i.e., crit, alert, emerg)
+.It
+Any message from any facility (*) at level err or higher
+(err, crit, alert, emerg)
+.El
+.Pp
+With this combination, a message from mail at level err will
+match *.err and be logged, even though it doesn’t meet mail.crit.
