• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y sang ((((ma hoi) OR (xa hoi))) or (mai hoi)). lieu va tham loc va danh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y sang ((((ma hoi) OR (xa hoi))) OR (mai hoi)). lieu va tham loc va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y sang ((((ma hoi) OR (xa hoi))) or (mai hoi)). lieu va tham loc va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y sang ((((ma hoi) OR (xa hoi))) or (mai hoi)). lieu va tham loc va danh vi cua tre*.
