• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - hanh trang ((tuan dung) OR (tuan duong)) cong tac ((tran chau) OR (ran cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - hanh trang ((tuan dung) OR (tuan duong)) cong tac ((tran chau) or (ran cau))".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - hanh trang ((tuan dung) OR (tuan duong)) cong tac ((tran chau) or (ran cau))*.
