Perhaps you should try some spelling variations:
"managing disruption" » "managing disruptions", "managing disruptive", "mating disruption"
"managing directors" » "managing director's", "managing defects", "managing distractions", "managing directorys", "managing directs"
"managing director" » "managing directory", "managing direct"

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 directors") OR ("managing director"))) OR ("managing disruption")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"managing directors\") OR (\"managing director\"))) or (\"managing disruption\"))".
• Removing quotes may allow a broader search: (((( managing directors ) OR ( managing director ))) or ( managing disruption )).
• Adding a wildcard symbol may retrieve word variants: (((("managing directors") OR ("managing director"))) or ("managing disruption"))*.
