Perhaps you should try some spelling variations:
"activatory" » "activators", "coactivators", "inactivators", "activationy", "activatedy", "activatey"
"activator" » "activation", "activated", "activate"
"actuar" » "actual"
"actuator" » "actuators"

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