• If you are trying to use Boolean operators, they must be ALL CAPS: (((("europe's income countries.") OR ((("european emerging countries.") OR ("european sending countries."))))) OR ("europe's arab countries."))*.
• Removing quotes may allow a broader search: (((( europe's income countries. ) or ((( european emerging countries. ) or ( european sending countries. ))))) or ( europe's arab countries. ))*.
