• 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 ((va cua) OR (via 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 ((va cua) OR (via 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 ((va cua) OR (via cua)) te*.
