• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang xa hoi. hieu van nam ((xua va) OR (sua va)) dinh ((van cuu) OR (van cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang xa hoi. hieu van nam ((xua va) OR (sua va)) dinh ((van cuu) or (van cau)) tre".
