• Performing a fuzzy search may retrieve terms with similar spellings: (((((("european union's countries.") or ((("european prone countries.") or ((("european five countries.") OR ("european firms 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 prone countries.") OR ((("european five countries.") OR ("european firms 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 prone countries.\") or (((\"european five countries.\") OR (\"european firms countries.\"))))))) or (\"europe's union countries.\"))) or (\"europe's arab countries.\"))".
• Removing quotes may allow a broader search: (((((( european union's countries. ) or ((( european prone countries. ) or ((( european five countries. ) OR ( european firms 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 prone countries.") or ((("european five countries.") OR ("european firms countries."))))))) or ("europe's union countries."))) or ("europe's arab countries."))*.
