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