• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang o hoi. lieu va ((cau luc) OR (cau phuc)) ban thanh moi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang o hoi. lieu va ((cau luc) OR (cau phuc)) ban thanh moi ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sach ty hang o hoi. lieu va ((cau luc) OR (cau phuc)) ban thanh moi ((cua tre) or (cua te))*.
