• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky dang)) lai hoi. hieu su chat ((xuc va) OR (duc va)) hanh vai cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) or (ky dang)) lai hoi. hieu su chat ((xuc va) OR (duc va)) hanh vai cua cu".
