• If you are trying to use Boolean operators, they must be ALL CAPS: wei ((yang yang) OR (wang yang)) iii gene wong hua ((zhong tai) OR (zhang zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wei ((yang yang) OR (wang yang)) iii gene wong hua ((zhong tai) or (zhang zhi)) ;*".
