• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - thanh trung ((cua trong) OR (cua trung)) cong dan ((gian cac) OR (gian cua))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh trung ((cua trong) OR (cua trung)) cong dan ((gian cac) or (gian cua))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - thanh trung ((cua trong) OR (cua trung)) cong dan ((gian cac) or (gian cua))*.
