• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) tinh - thanh ((trung quan) OR (trung tuan)) nhung song van thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) tinh - thanh ((trung quan) OR (trung tuan)) nhung song van thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) tinh - thanh ((trung quan) OR (trung tuan)) nhung song van thanh lap*.
