• If you are trying to use Boolean operators, they must be ALL CAPS: te sach uu hang va hoa. hieu ((vien cac) OR (vien da)) ((xuc van) OR (luc van)) hanh de cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach uu hang va hoa. hieu ((vien cac) OR (vien da)) ((xuc van) or (luc van)) hanh de cuu tre*".
