• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky sang lap hai. hieu ((((ve cham) OR (vu cham))) or (ve cac)) loc va dan vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang lap hai. hieu ((((ve cham) OR (vu cham))) OR (ve cac)) loc va dan vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang lap hai. hieu ((((ve cham) OR (vu cham))) or (ve cac)) loc va dan vi cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky sang lap hai. hieu ((((ve cham) OR (vu cham))) or (ve cac)) loc va dan vi cua te*.
