• Performing a fuzzy search may retrieve terms with similar spellings: su sach y tang ma hoi. hieu ((ve cam) or (ve cac)) ((tuc van) OR (tuc va)) thanh vi cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y tang ma hoi. hieu ((ve cam) OR (ve cac)) ((tuc van) OR (tuc va)) thanh vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y tang ma hoi. hieu ((ve cam) or (ve cac)) ((tuc van) OR (tuc va)) thanh vi cau treo".
• Adding a wildcard symbol may retrieve word variants: su sach y tang ma hoi. hieu ((ve cam) or (ve cac)) ((tuc van) OR (tuc va)) thanh vi cau treo*.
