• Performing a fuzzy search may retrieve terms with similar spellings: (((((("european union's countries.") or ((((("european emerging countries.") OR ("european lagging countries."))) or ("european sending countries."))))) or ("europe's union countries."))) or ("europe's arab countries."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("european union's countries.") OR ((((("european emerging countries.") OR ("european lagging countries."))) OR ("european sending countries."))))) OR ("europe's union countries."))) OR ("europe's arab countries.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"european union's countries.\") or (((((\"european emerging countries.\") OR (\"european lagging countries.\"))) or (\"european sending countries.\"))))) or (\"europe's union countries.\"))) or (\"europe's arab countries.\"))".
• Removing quotes may allow a broader search: (((((( european union's countries. ) or ((((( european emerging countries. ) OR ( european lagging countries. ))) or ( european sending countries. ))))) or ( europe's union countries. ))) or ( europe's arab countries. )).
• Adding a wildcard symbol may retrieve word variants: (((((("european union's countries.") or ((((("european emerging countries.") OR ("european lagging countries."))) or ("european sending countries."))))) or ("europe's union countries."))) or ("europe's arab countries."))*.
