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