• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach _ sang mai hoi. ((hieu va) OR (lieu va)) cham xuc ca dan lai ((dung trung) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach _ sang mai hoi. ((hieu va) OR (lieu va)) cham xuc ca dan lai ((dung trung) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach _ sang mai hoi. ((hieu va) OR (lieu va)) cham xuc ca dan lai ((dung trung) or (cua te))*.
