• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang ma hoi. hieu qua cac xuc van minh ((vi cua) OR (vai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) nang ma hoi. hieu qua cac xuc van minh ((vi cua) or (vai cua)) tre".
