• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - thanh dung dat dung ((trong ban) OR (trong san)) than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - thanh dung dat dung ((trong ban) or (trong san)) than cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - thanh dung dat dung ((trong ban) or (trong san)) than cao*.
