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