• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - thanh hang va duong trong ((van toan) OR (van thanh)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - thanh hang va duong trong ((van toan) or (van thanh)) tap*".
