• If you are trying to use Boolean operators, they must be ALL CAPS: wang yao yang july gene yang kim ((((young hr) OR (young 4))) OR (young let)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yao yang july gene yang kim ((((young hr) OR (young 4))) or (young let)) ;*".
