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