The API added for fetching circulation rules in bug 36641 allows for limiting which rules you wish to have returned by passing a comma delimited list of rules names in the ?rules= param. We could enhance this to allow for wildcards and open up the opportunity for returning sets of related rules based on a common prefix in the rule name. For example.. `?rules=recalls_*,overdue*` would return all recalls_ and overdue rules without having to specify each of them individually in the query.
