• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((anh dang) OR (anh sang)) ((chua bang) OR (chu bang)) song dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((anh dang) or (anh sang)) ((chua bang) OR (chu bang)) song dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((anh dang) or (anh sang)) ((chua bang) OR (chu bang)) song dan toan ban*.
