• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky dang ((ma hoi) OR (mai hoi)). hieu ve ((chat duc) or (chat xuc)) va thanh tap cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky dang ((ma hoi) OR (mai hoi)). hieu ve ((chat duc) OR (chat xuc)) va thanh tap cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky dang ((ma hoi) OR (mai hoi)). hieu ve ((chat duc) or (chat xuc)) va thanh tap cua te".
