• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yunling liang ((a gene) OR (e gene)) tas tan ((((zhong tai) OR (hong tan))) OR (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yunling liang ((a gene) OR (e gene)) tas tan ((((zhong tai) OR (hong tan))) OR (hong ng)) ;*.
