• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. lieu va ((nam xuc) OR (nam xua)) ((va thanh) OR (ban thanh)) dien ca viet.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. lieu va ((nam xuc) or (nam xua)) ((va thanh) or (ban thanh)) dien ca viet*.
