• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - hanh trang cua ((phong trong) OR (khong trong)) tan tran cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - hanh trang cua ((phong trong) or (khong trong)) tan tran cau*".
