• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang xa hoi. hieu ve chat xuc va ((hanh lai) OR (hanh tai)) ((dua tren) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang xa hoi. hieu ve chat xuc va ((hanh lai) OR (hanh tai)) ((dua tren) or (cuu tre))*".
