• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xay hoi. hieu ve cac xuc ((((ban hang) OR (ngan hang))) or (quan anh)) dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xay hoi. hieu ve cac xuc ((((ban hang) OR (ngan hang))) OR (quan anh)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xay hoi. hieu ve cac xuc ((((ban hang) OR (ngan hang))) or (quan anh)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky dang xay hoi. hieu ve cac xuc ((((ban hang) OR (ngan hang))) or (quan anh)) dai cua tre*.
