• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((((ve cam) OR (vu cham))) OR (va cam)) tuc va hanh vi cua te.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ((((ve cam) or (vu cham))) or (va cam)) tuc va hanh vi cua te*.
