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