• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang cho hoc. hieu ve cac xuc ((((van hanh) OR (ban hanh))) or (van anh)) vai cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang cho hoc. hieu ve cac xuc ((((van hanh) OR (ban hanh))) OR (van anh)) vai cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang cho hoc. hieu ve cac xuc ((((van hanh) OR (ban hanh))) or (van anh)) vai cua cau*".
