Perhaps you should try some spelling variations:
"managing subscriptions" » "taking subscriptions", "concerning subscriptions"
"managing disruptions" » "managing distractions", "mating disruption", "managing interruptions", "managing disruptives", "mating disruptions", "manage disruptions"
"managing disruption" » "managing disruptive", "mating disruption", "manage disruption"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("managing disruption") OR ((("managing disruptions") OR ("managing subscriptions")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"managing disruption\") or (((\"managing disruptions\") OR (\"managing subscriptions\"))))".
• Removing quotes may allow a broader search: (( managing disruption ) or ((( managing disruptions ) OR ( managing subscriptions )))).
• Adding a wildcard symbol may retrieve word variants: (("managing disruption") or ((("managing disruptions") OR ("managing subscriptions"))))*.
