• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach kem) OR (sach y)) dang xay hoi. hieu van nam xuc ((va dinh) OR (va kinh)) ke cau tra.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach kem) or (sach y)) dang xay hoi. hieu van nam xuc ((va dinh) OR (va kinh)) ke cau tra".
• Adding a wildcard symbol may retrieve word variants: te ((sach kem) or (sach y)) dang xay hoi. hieu van nam xuc ((va dinh) OR (va kinh)) ke cau tra*.
