• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (so sach)) y dang cay phoi. hieu ve cac tuc va ((hang dai) OR (hang dau)) va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (so sach)) y dang cay phoi. hieu ve cac tuc va ((hang dai) OR (hang dau)) va triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (so sach)) y dang cay phoi. hieu ve cac tuc va ((hang dai) OR (hang dau)) va triet*.
