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