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