• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - canh tranh cua bang ((((song dan) OR (cong dan))) OR (song van)) than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - canh tranh cua bang ((((song dan) OR (cong dan))) or (song van)) than cao".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - canh tranh cua bang ((((song dan) OR (cong dan))) or (song van)) than cao*.
