• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - canh tranh tuan dung hong anh ((tuan cu) OR (tuan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu sang)) - canh tranh tuan dung hong anh ((tuan cu) OR (tuan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chieu sang)) - canh tranh tuan dung hong anh ((tuan cu) OR (tuan tu))*.
