• If you are trying to use Boolean operators, they must be ALL CAPS: wing wang yang ((((hua gene) OR (hua ren))) OR (a gene)) bank die ((wong sam) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing wang yang ((((hua gene) OR (hua ren))) or (a gene)) bank die ((wong sam) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing wang yang ((((hua gene) OR (hua ren))) or (a gene)) bank die ((wong sam) or (kong sar)) ;*.
