• If you are trying to use Boolean operators, they must be ALL CAPS: zhang (yuqin OR yuqing) can ((china won) OR (((china wang) OR (china chang)))) yang jie chang ha ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang (yuqin or yuqing) can ((china won) or (((china wang) OR (china chang)))) yang jie chang ha ;~".
• Adding a wildcard symbol may retrieve word variants: zhang (yuqin or yuqing) can ((china won) or (((china wang) OR (china chang)))) yang jie chang ha ;*.
