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