• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang o) OR (nang co)) hai. hieu va cam xuc ban danh ((di cua) OR (doi cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang o) or (nang co)) hai. hieu va cam xuc ban danh ((di cua) OR (doi cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang o) or (nang co)) hai. hieu va cam xuc ban danh ((di cua) OR (doi cua)) te*.
