• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) ((yang yang) OR (yin fang)) ((cio best) OR (can best)) china hong cheng lu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((yang yang) or (yin fang)) ((cio best) OR (can best)) china hong cheng lu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((yang yang) or (yin fang)) ((cio best) OR (can best)) china hong cheng lu ;*.
