• If you are trying to use Boolean operators, they must be ALL CAPS: wan dan yang ((davis best) OR (davis test)) yang ((kim dong) OR (kim jong)) (sin OR wind) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan dan yang ((davis best) OR (davis test)) yang ((kim dong) or (kim jong)) (sin or wind) ;~".
• Adding a wildcard symbol may retrieve word variants: wan dan yang ((davis best) OR (davis test)) yang ((kim dong) or (kim jong)) (sin or wind) ;*.
