Perhaps you should try some spelling variations:
"diplomat" » "diplomatic", "diplom", "diplomt"
"diplomatie" » "diplomaticie", "diplomie", "diplomatic", "diplomtie"
"diplomats" » "diplomatics", "diploms", "diplomts", "diplomatic"
"diploma" » "diplom"
"diplomacys" » "diplomcys", "diplomacies", "diplomas", "diplomacia"
"diplomacy" » "diplomcy"

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