• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - hanh trong quang ((truong luong) OR (truong huong)) ((va tuan) OR (va quan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - hanh trong quang ((truong luong) OR (truong huong)) ((va tuan) or (va quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - hanh trong quang ((truong luong) OR (truong huong)) ((va tuan) or (va quan)) cau*.
