Perhaps you should try some spelling variations:
"diplomat" » "diplomatie", "diplomacy", "diplom", "diplomt", "diplomacyt"
"diplomats" » "diplomaties", "diplomacys", "diploms", "diplomts", "diplomacyts", "diplomacy"
"diplomatic" » "diplomatieic", "diplomacyic", "diplomic", "diplomtic", "diplomacytic"
"diplomaties" » "diplomatieies", "diplomacyies", "diplomies", "diplomties", "diplomacyties", "diplomatie", "diplomatics", "diplomacies"
"diploma" » "diplom", "diplomacy"
"diplomts" » "diplomes", "diplomas", "diploms"

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