• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (((v nang) OR (vu nang)))) co hoi. hieu van ban truc va nhanh ha cuu tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ((y nang) or (((v nang) OR (vu nang)))) co hoi. hieu van ban truc va nhanh ha cuu tre*.
