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