Perhaps you should try some spelling variations:
"diplomat" » "diplomats", "diplomatie", "diplom", "diplomt", "diplomatst"
"diplomatic" » "diplomatsic", "diplomatieic", "diplomic", "diplomtic", "diplomatstic"
"diplomacy" » "diplomcy", "diplomatscy"
"diploma" » "diplom", "diplomats"
"diplomacys" » "diplomcys", "diplomatscys", "diplomacies", "diplomats", "diplomas"

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: ((("diplomat" OR "diplomacy") OR "diploma") OR ("diplomatic" OR "diplomacys")).
• Removing quotes may allow a broader search: ((( diplomat or diplomacy ) or diploma ) or ( diplomatic or diplomacys )).
• Adding a wildcard symbol may retrieve word variants: ((("diplomat" or "diplomacy") or "diploma") or ("diplomatic" or "diplomacys"))*.
