• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (dang van)) hoi. hieu qua cac xuc ban hanh ((thai cua) OR (than cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) or (dang van)) hoi. hieu qua cac xuc ban hanh ((thai cua) OR (than cua)) tre*".
