• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (nhieu tang)) - thanh truong cao hang ((cong van) OR (cong vang)) tan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) or (nhieu tang)) - thanh truong cao hang ((cong van) OR (cong vang)) tan cao~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) or (nhieu tang)) - thanh truong cao hang ((cong van) OR (cong vang)) tan cao*.
