• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. lieu va cam tuc va kinh kien ((((cau treo) OR (cau theo))) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. lieu va cam tuc va kinh kien ((((cau treo) OR (cau theo))) or (cau tren))".
