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