• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (((ha tinh) OR (may tinh)))) - thanh trung cap thong song van than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (((ha tinh) OR (may tinh)))) - thanh trung cap thong song van than cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (((ha tinh) OR (may tinh)))) - thanh trung cap thong song van than cap*.
