Perhaps you should try some spelling variations:
"diplomat" » "diplomatic", "diplomatie", "diplomacy", "diplomt", "diplomacyt"
"diplomats" » "diplomatics", "diplomaties", "diplomacys", "diplomts", "diplomacyts", "diplomatic", "diplomacy"
"diplomatics" » "diplomaticics", "diplomatieics", "diplomacyics", "diplomtics", "diplomacytics", "diplomatic", "diplomatie", "diplomatische"

"diplomacyties" » "diplomcyties", "diplomacycyties", "diplomatie", "diplomates"
"diplomacies" » "diplomcies", "diplomacycies", "diplomatie", "diplomacia", "diplomates"

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