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