• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu nang tai khoa. hieu ((qua cam) OR (qua cac)) ((xuc van) OR (duc van)) dang van cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu nang tai khoa. hieu ((qua cam) OR (qua cac)) ((xuc van) or (duc van)) dang van cua tu*".
