• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang xay hoi. lieu va nam duc ((manh thanh) OR (manh thang)) lap ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang xay hoi. lieu va nam duc ((manh thanh) OR (manh thang)) lap ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sach ty dang xay hoi. lieu va nam duc ((manh thanh) OR (manh thang)) lap ((cua tre) or (cua te))*.
