• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien tach - ((hanh trung) OR (hanh trang)) ha nhung duong manh ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien tach - ((hanh trung) or (hanh trang)) ha nhung duong manh ((toan cau) OR (toan cao))".
