• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan guan) OR (gan guan)) ((1 gene) OR (((a gene) OR (a genre)))) w can one sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan guan) or (gan guan)) ((1 gene) or (((a gene) OR (a genre)))) w can one sau ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan guan) or (gan guan)) ((1 gene) or (((a gene) OR (a genre)))) w can one sau ;*.
