• If you are trying to use Boolean operators, they must be ALL CAPS: zhang zhang can e ((gene one) OR (((gene we) OR (gene w)))) than deep sub ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang zhang can e ((gene one) or (((gene we) OR (gene w)))) than deep sub ;".
• Adding a wildcard symbol may retrieve word variants: zhang zhang can e ((gene one) or (((gene we) OR (gene w)))) than deep sub ;*.
