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