• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((((ky tang) OR (kho tang))) or (ky dang)) xa hoi. hieu va cao xuc va thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((((ky tang) OR (kho tang))) OR (ky dang)) xa hoi. hieu va cao xuc va thanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((((ky tang) OR (kho tang))) or (ky dang)) xa hoi. hieu va cao xuc va thanh vai cua tre*".
