• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((y nang) OR (ly nang)) xa hoi. hieu ve ((cham xuc) OR (cham soc)) va phan thai va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((y nang) or (ly nang)) xa hoi. hieu ve ((cham xuc) OR (cham soc)) va phan thai va thiet".
• Adding a wildcard symbol may retrieve word variants: vu sach ((y nang) or (ly nang)) xa hoi. hieu ve ((cham xuc) OR (cham soc)) va phan thai va thiet*.
