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