"international water" » "international patient", "international law", "international trade"
"international actor" » "international edition"

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