• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((((ngan hoa) OR (nhan hoa))) or (nganh khoa)) hi đong luc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((ngan hoa) OR (nhan hoa))) OR (nganh khoa)) hi đong luc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((ngan hoa) OR (nhan hoa))) or (nganh khoa)) hi đong luc".
• Adding a wildcard symbol may retrieve word variants: te sach ((((ngan hoa) OR (nhan hoa))) or (nganh khoa)) hi đong luc*.
