• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky long) OR (sy long)) ha hoi. hieu ((van cam) OR (van nam)) duc ban hanh va chua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky long) OR (sy long)) ha hoi. hieu ((van cam) or (van nam)) duc ban hanh va chua tre".
