Perhaps you should try some spelling variations:
"international waters" » "international patient", "international actor", "international watercourses", "international actors", "international patients", "international laws"
"international water" » "international actor", "international patient", "international law"
"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 waters") or ((("international laws") OR ("international 4"))))) or ("international water"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("international waters") OR ((("international laws") OR ("international 4"))))) OR ("international water"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"international waters\") or (((\"international laws\") OR (\"international 4\"))))) or (\"international water\"))*".
• Removing quotes may allow a broader search: (((( international waters ) or ((( international laws ) OR ( international 4 ))))) or ( international water ))*.
