• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang co loi. hieu ve cam ((xac va) or (((tuc va) OR (truc va)))) thanh loi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang co loi. hieu ve cam ((xac va) OR (((tuc va) OR (truc va)))) thanh loi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang co loi. hieu ve cam ((xac va) or (((tuc va) OR (truc va)))) thanh loi cua tre*".
