• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh dang ha thanh long van ((toan ban) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh dang ha thanh long van ((toan ban) or (van ban))".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh dang ha thanh long van ((toan ban) or (van ban))*.
