• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang xa hoi. ((lieu van) OR (lieu va)) ((cau duc) OR (cau luc)) va danh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang xa hoi. ((lieu van) or (lieu va)) ((cau duc) OR (cau luc)) va danh vai cua tre".
