• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yin hang) OR (yin fang))) OR (wang yang)) ((yang jui) OR (yang di)) jing fang yuan zhang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yin hang) OR (yin fang))) or (wang yang)) ((yang jui) or (yang di)) jing fang yuan zhang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yin hang) OR (yin fang))) or (wang yang)) ((yang jui) or (yang di)) jing fang yuan zhang zhi ;*.
