• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao yang ((((hua chen) OR (a chen))e) OR (((hua chen) OR (a chen)))) chan eng hong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao yang ((((hua chen) OR (a chen))e) or (((hua chen) OR (a chen)))) chan eng hong shu ;".
• Adding a wildcard symbol may retrieve word variants: wang yao yang ((((hua chen) OR (a chen))e) or (((hua chen) OR (a chen)))) chan eng hong shu ;*.
