• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang xa hoi. hieu ve cam xuc ban ((hanh lai) OR (hanh lam)) ((chau tre) OR (chay tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang xa hoi. hieu ve cam xuc ban ((hanh lai) OR (hanh lam)) ((chau tre) or (chay tren))".
