• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang ma hoi. ((hieu van) OR (thien van)) cam tuc ((xa hanh) OR (xa khanh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ma hoi. ((hieu van) OR (thien van)) cam tuc ((xa hanh) or (xa khanh)) vai cua tre*".
