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