• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan ting) OR (yuan lin))) OR (huang ting)) wang human gene ying jin hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan ting) OR (yuan lin))) or (huang ting)) wang human gene ying jin hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yuan ting) OR (yuan lin))) or (huang ting)) wang human gene ying jin hong shu ;*.
