• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang son hai. hieu va cam ((xuat ban) or (duc ban)) ((anh di) OR (danh di)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang son hai. hieu va cam ((xuat ban) OR (duc ban)) ((anh di) OR (danh di)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang son hai. hieu va cam ((xuat ban) or (duc ban)) ((anh di) OR (danh di)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang son hai. hieu va cam ((xuat ban) or (duc ban)) ((anh di) OR (danh di)) cua tre*.
