• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) dang xa hoi. ((hieu ve) OR (hieu van)) cac tuc va danh ban cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sac ky)) dang xa hoi. ((hieu ve) OR (hieu van)) cac tuc va danh ban cuu tre*".
