Perhaps you should try some spelling variations:
"diplomat" » "diploma", "diplomatic", "diplomatie"
"diplomats" » "diplomas", "diplomatics", "diplomaties", "diplomatic", "diplomacy"
"diplomacys" » "diplomacy", "diplomacies", "diplomas"
"diplomcys" » "diplomacy", "diplomes", "diplomas"

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 "diplomats") OR ("diplomacys" OR "diplomcys")).
• Removing quotes may allow a broader search: (( diplomat or diplomats ) or ( diplomacys or diplomcys )).
• Adding a wildcard symbol may retrieve word variants: (("diplomat" or "diplomats") or ("diplomacys" or "diplomcys"))*.
