• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tay tang ma hoi. hieu ve cham ((((luc van) OR (duc van))) OR (luoc van)) hanh tai cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tay tang ma hoi. hieu ve cham ((((luc van) OR (duc van))) or (luoc van)) hanh tai cua vat*".
