Perhaps you should try some spelling variations:
"international patient" » "international student", "international water", "international students"
"international waters" » "international water", "international watercourses", "international law"
"international joint" » "international journal", "international issn", "international tourists"
"international actor" » "international water", "international edition"

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: (((("international waters") OR ((("international patient") OR ("international joint"))))) OR ("international actor"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"international waters\") or (((\"international patient\") OR (\"international joint\"))))) or (\"international actor\"))~".
• Removing quotes may allow a broader search: (((( international waters ) or ((( international patient ) OR ( international joint ))))) or ( international actor ))~.
• Adding a wildcard symbol may retrieve word variants: (((("international waters") or ((("international patient") OR ("international joint"))))) or ("international actor"))*.
