Perhaps you should try some spelling variations:
"international patient" » "international student", "international joint", "international students"
"international waters" » "international actor", "international watercourses", "international law", "international actors", "international laws", "international transfers"
"international water" » "international actor", "international law", "international transfer"
"international trade" » "international law", "international student", "international finance"

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