• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh trang va tong cong ((((dan thanh) OR (dang thanh))) OR (van thanh)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh trang va tong cong ((((dan thanh) OR (dang thanh))) or (van thanh)) cao*".
