• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) dang xay hoi. ((hieu ve) OR (hieu va)) cam xuc ban manh tai cuc triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach y)) dang xay hoi. ((hieu ve) or (hieu va)) cam xuc ban manh tai cuc triet".
