• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. hieu van cam ((loc van) OR (luoc van)) hanh ((tai cua) OR (tai cuc)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. hieu van cam ((loc van) OR (luoc van)) hanh ((tai cua) or (tai cuc)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach ky lang xa hoi. hieu van cam ((loc van) OR (luoc van)) hanh ((tai cua) or (tai cuc)) te*.
