• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang yera) OR (yang yang)) yu chen huang jia ((((zhang yu) OR (zhang yi))) OR (zhang ya)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang yera) or (yang yang)) yu chen huang jia ((((zhang yu) OR (zhang yi))) or (zhang ya)) ;*".
