• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((tu nang) OR (tu nano)) ((me 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 ((tu nang) OR (tu nano)) ((me hoi) or (mai hoi)). hieu ve cam xuc va dinh di cua te".
