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