• If you are trying to use Boolean operators, they must be ALL CAPS: te sach vu cong ((ha hoi) OR (ha noi)). hieu van ((chat xuc) OR (cam xuc)) va ban va cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach vu cong ((ha hoi) OR (ha noi)). hieu van ((chat xuc) or (cam xuc)) va ban va cuu tre".
