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