Perhaps you should try some spelling variations:
"diplomat" » "diplomatic", "diplomatie", "diplom", "diplomt"
"diplomats" » "diplomatics", "diplomaties", "diploms", "diplomts", "diplomatic"
"diplomatics" » "diplomaticics", "diplomatieics", "diplomics", "diplomtics", "diplomatic", "diplomatie", "diplomatische"
"diploma" » "diplom"
"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 ("diploma" OR "diplomacy")) OR ("diplomats" OR "diplomatics")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"diplomat\" or (\"diploma\" OR \"diplomacy\")) or (\"diplomats\" or \"diplomatics\"))".
• Removing quotes may allow a broader search: (( diplomat or ( diploma OR diplomacy )) or ( diplomats or diplomatics )).
• Adding a wildcard symbol may retrieve word variants: (("diplomat" or ("diploma" OR "diplomacy")) or ("diplomats" or "diplomatics"))*.
