• If you are trying to use Boolean operators, they must be ALL CAPS: ((((lang yan) OR (wang yang))) OR (((huang jing) OR (huang yang)))) yang di i und john wong siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((lang yan) OR (wang yang))) or (((huang jing) or (huang yang)))) yang di i und john wong siu ;*".
