• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ky nang)) xa hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ky nang)) xa hoi. ((hieu ve) or (hieu va)) cam xuc va hanh vi cua triet".
