• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((nhieu tang) OR (chieu sang)) - ((anh bang) OR (hanh trang)) cua thong cong ban hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((nhieu tang) OR (chieu sang)) - ((anh bang) or (hanh trang)) cua thong cong ban hang cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((nhieu tang) OR (chieu sang)) - ((anh bang) or (hanh trang)) cua thong cong ban hang cau*.
