• If you are trying to use Boolean operators, they must be ALL CAPS: wang jan a head tan ((dong jung) OR (dong yang)) ((chang ha) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang jan a head tan ((dong jung) OR (dong yang)) ((chang ha) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang jan a head tan ((dong jung) OR (dong yang)) ((chang ha) or (zhong zhi)) ;*.
