Perhaps you should try some spelling variations:
"diplomat" » "diplomatic", "diplomatie", "diplom", "diplomt"
"diplomats" » "diplomatics", "diplomaties", "diploms", "diplomts", "diplomatic"
"diplomacyt" » "diplomacia", "diplomancy", "diplomcyt"
"diploma" » "diplom"
"diplomacy" » "diplomcy"
"diplomcy" » "diplomancy", "diplom", "diplomes"

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