• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((dang xay) OR (van xay)) hoi. hieu ve cam loc va ((dinh tai) OR (dinh van)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((dang xay) OR (van xay)) hoi. hieu ve cam loc va ((dinh tai) or (dinh van)) cuu tre*".
