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