• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (nang x)) hoi. thi van cac nuoc ban thanh lap ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (nang x)) hoi. thi van cac nuoc ban thanh lap ((cua viet) OR (ca viet))".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) or (nang x)) hoi. thi van cac nuoc ban thanh lap ((cua viet) OR (ca viet))*.
