• If you are trying to use Boolean operators, they must be ALL CAPS: ((chan kang) OR (chung kang)) ((hang china) OR (ghana china)) rate yang tin hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chan kang) or (chung kang)) ((hang china) OR (ghana china)) rate yang tin hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((chan kang) or (chung kang)) ((hang china) OR (ghana china)) rate yang tin hong yu ;*.
