Perhaps you should try some spelling variations:
"diplomt" » "diplomat", "diplome", "diploms"
"diploma" » "diplomacy"
"diplomats" » "diplomacyts", "diplomatic", "diplomacy"
"diplomaties" » "diplomacyties", "diplomatie", "diplomatics", "diplomacies"

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