• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sac ky)) nang xa hoi. hieu ve ((cham luc) OR (nhan luc)) vay doanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sac ky)) nang xa hoi. hieu ve ((cham luc) OR (nhan luc)) vay doanh va cua tre*".
