• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (((chieu xanh) OR (chieu sach)))) - hanh trang va nhung cong san thai cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) or (((chieu xanh) OR (chieu sach)))) - hanh trang va nhung cong san thai cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (((chieu xanh) OR (chieu sach)))) - hanh trang va nhung cong san thai cao*.
