Perhaps you should try some spelling variations:
"international tourists" » "international students", "international journal"
"international waters" » "international patient", "international actor", "international law", "international actors", "international patients", "international laws"
"international watercourses" » "international actorcourses", "international patientcourses", "international lawcourses"
"international water" » "international actor", "international patient", "international law"

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