• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tu)) xang xa hoi. lieu va nham thuc ((va thanh) OR (gia thanh)) vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach tu)) xang xa hoi. lieu va nham thuc ((va thanh) or (gia thanh)) vi cua tu".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach tu)) xang xa hoi. lieu va nham thuc ((va thanh) or (gia thanh)) vi cua tu*.
