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