• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - ((hanh truong) OR (anh truong)) cao thong thong van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu tinh)) - ((hanh truong) or (anh truong)) cao thong thong van toan cau*".
