Perhaps you should try some spelling variations:
"diplomat" » "diplomats", "diplomatic", "diplomacy", "diplomt", "diplomacyt", "diplomatst"
"diplomatie" » "diplomatsie", "diplomaticie", "diplomacyie", "diplomatic", "diplomats", "diplomtie", "diplomacytie", "diplomatstie"
"diploma" » "diplom", "diplomacy", "diplomats"

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