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