• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong ryangg) OR (wang yan)) rryana hua test yang yang ((long yu) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong ryangg) or (wang yan)) rryana hua test yang yang ((long yu) OR (long du)) ;*".
