• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly quang xa hoi. hieu van hau duc va kinh ((((di cua) OR (doi cua))) OR (dai cua)) viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly quang xa hoi. hieu van hau duc va kinh ((((di cua) OR (doi cua))) or (dai cua)) viet".
