• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) nang tai hoi. hieu ve cham duc van ((anh vi) OR (anh va)) su viet~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach y)) nang tai hoi. hieu ve cham duc van ((anh vi) or (anh va)) su viet*.
