• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((nha ke) OR (nha k2)) nguoi ha hoang minh ) OR ( tu sach nha xe giai can hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((nha ke) OR (nha k2)) nguoi ha hoang minh ) or ( tu sach nha xe giai can hoang minh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((nha ke) OR (nha k2)) nguoi ha hoang minh ) or ( tu sach nha xe giai can hoang minh ))*.
