• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tu)) dang xay hoi. hieu ve cam luc ((van hang) OR (van thang)) va cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach tu)) dang xay hoi. hieu ve cam luc ((van hang) OR (van thang)) va cua te~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach tu)) dang xay hoi. hieu ve cam luc ((van hang) OR (van thang)) va cua te*.
