• Performing a fuzzy search may retrieve terms with similar spellings: so sach tay lang ha hoi. hieu ((van cau) or (van nam)) loc ((va hanh) OR (va danh)) vi cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach tay lang ha hoi. hieu ((van cau) OR (van nam)) loc ((va hanh) OR (va danh)) vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach tay lang ha hoi. hieu ((van cau) or (van nam)) loc ((va hanh) OR (va danh)) vi cau treo".
• Adding a wildcard symbol may retrieve word variants: so sach tay lang ha hoi. hieu ((van cau) or (van nam)) loc ((va hanh) OR (va danh)) vi cau treo*.
