• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((hang cau) OR (hang dau)) hoi. hieu ve cam duc va thanh va ((luu tru) OR (luy tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((hang cau) OR (hang dau)) hoi. hieu ve cam duc va thanh va ((luu tru) or (luy tre))".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((hang cau) OR (hang dau)) hoi. hieu ve cam duc va thanh va ((luu tru) or (luy tre))*.
