Perhaps you should try some spelling variations:
"international patient" » "international student", "international joint", "international students"
"international waters" » "international watercourses", "international trade", "international trades", "international transfers"
"international actor" » "international edition"
"international water" » "international trade", "international transfer"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("international waters") or ((("international actor") or ((("international water") OR ("international law"))))))) or ("international patient"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("international waters") OR ((("international actor") OR ((("international water") OR ("international law"))))))) OR ("international patient")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"international waters\") or (((\"international actor\") or (((\"international water\") OR (\"international law\"))))))) or (\"international patient\"))".
• Removing quotes may allow a broader search: (((( international waters ) or ((( international actor ) or ((( international water ) OR ( international law ))))))) or ( international patient )).
• Adding a wildcard symbol may retrieve word variants: (((("international waters") or ((("international actor") or ((("international water") OR ("international law"))))))) or ("international patient"))*.
