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