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