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