• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty tang) OR (ty xang)) ((ma hoi) OR (xa hoi)). hieu vu kham duc van thanh lam cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty tang) OR (ty xang)) ((ma hoi) or (xa hoi)). hieu vu kham duc van thanh lam cua tre*".
