• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) lang xa hoi. hieu vien bach xuc va thanh ((va cua) OR (via cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (dan ky)) lang xa hoi. hieu vien bach xuc va thanh ((va cua) or (via cua)) tre".
