• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang wang ((a gene) OR (a genre)) ((gong min) OR (gong minh)) jeong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang ((a gene) OR (a genre)) ((gong min) or (gong minh)) jeong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang wang ((a gene) OR (a genre)) ((gong min) or (gong minh)) jeong ghi ;*.
