• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ty) OR (sach thu)) nang ((ma hoi) OR (mai hoi)). hieu ve cam xuc va dinh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) OR (sach thu)) nang ((ma hoi) or (mai hoi)). hieu ve cam xuc va dinh di cua te".
