• Performing a fuzzy search may retrieve terms with similar spellings: te sach _ ((sang ma) OR (nang ma)) hoi. hieu va cam tuc ((va thanh) or (gia thanh)) thai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach _ ((sang ma) OR (nang ma)) hoi. hieu va cam tuc ((va thanh) OR (gia thanh)) thai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach _ ((sang ma) OR (nang ma)) hoi. hieu va cam tuc ((va thanh) or (gia thanh)) thai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach _ ((sang ma) OR (nang ma)) hoi. hieu va cam tuc ((va thanh) or (gia thanh)) thai cuu tre*.
