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