• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu bang ma hoi. hieu va ((cac xuc) OR (cam xuc)) ((va thanh) or (ban hanh)) vi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu bang ma hoi. hieu va ((cac xuc) OR (cam xuc)) ((va thanh) OR (ban hanh)) vi cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu bang ma hoi. hieu va ((cac xuc) OR (cam xuc)) ((va thanh) or (ban hanh)) vi cua viet*".
