• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (yang yang)) yang ((li gene) OR (l1 gene)) long thanh wong laid ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) OR (yang yang)) yang ((li gene) or (l1 gene)) long thanh wong laid ;*".
