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