• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach v) OR (sach va)) nang xa hoi. hieu ve cac truc tran hong di ((cua viet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach v) OR (sach va)) nang xa hoi. hieu ve cac truc tran hong di ((cua viet) or (su triet))".
