• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((tang min) OR (chang min)) ((yuan yi) OR (yuan zi)) yang yi fang zheng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((tang min) OR (chang min)) ((yuan yi) or (yuan zi)) yang yi fang zheng ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((tang min) OR (chang min)) ((yuan yi) or (yuan zi)) yang yi fang zheng ;*.
