• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach _ lang van hoe. ((hieu va) OR (hieu qua)) cao xuc va hanh ((tai cua) OR (tai cuc)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach _ lang van hoe. ((hieu va) or (hieu qua)) cao xuc va hanh ((tai cua) OR (tai cuc)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach _ lang van hoe. ((hieu va) or (hieu qua)) cao xuc va hanh ((tai cua) OR (tai cuc)) te*.
