• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) nang xa hoi. ((hieu cao) or (hieu cac)) chat truc va danh dau cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) nang xa hoi. ((hieu cao) or (hieu cac)) chat truc va danh dau cua tre*.
