Perhaps you should try some spelling variations:
"international patient" » "international student", "international joint", "international students"
"international water" » "international actor", "international law", "international trade"
"international laws" » "international law", "international trade", "international _"
"international 4" » "international _", "international law", "international issn"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("international laws") OR ("international 4"))) or ((("international patient") or ("international water"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("international laws") OR ("international 4"))) OR ((("international patient") OR ("international water")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"international laws\") OR (\"international 4\"))) or (((\"international patient\") or (\"international water\"))))".
• Removing quotes may allow a broader search: (((( international laws ) OR ( international 4 ))) or ((( international patient ) or ( international water )))).
• Adding a wildcard symbol may retrieve word variants: (((("international laws") OR ("international 4"))) or ((("international patient") or ("international water"))))*.
