• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky sang tao hoi. hieu ve cam ((xuc va) OR (loc va)) hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky sang tao hoi. hieu ve cam ((xuc va) or (loc va)) hanh vi cua te".
