• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang ((ma hoi) or (mai khoi)). lieu va cam ((xuc gia) OR (luc gia)) thanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang ((ma hoi) OR (mai khoi)). lieu va cam ((xuc gia) OR (luc gia)) thanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang ((ma hoi) or (mai khoi)). lieu va cam ((xuc gia) OR (luc gia)) thanh vai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang ((ma hoi) or (mai khoi)). lieu va cam ((xuc gia) OR (luc gia)) thanh vai cua triet*.
