• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yanling ((((tan ching) OR (tan cheng))) OR (taiwan china)) wen yong jing fang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yanling ((((tan ching) OR (tan cheng))) or (taiwan china)) wen yong jing fang han ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yanling ((((tan ching) OR (tan cheng))) or (taiwan china)) wen yong jing fang han ;*.
