• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky xanh) OR (ky hanh)) ca phoi. ((hieu ve) OR (thien van)) cam duc ban anh tho cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky xanh) OR (ky hanh)) ca phoi. ((hieu ve) or (thien van)) cam duc ban anh tho cua te".
