• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky dang xay hoi. hieu ((ve pham) OR (ke phan)) duc va dinh van cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te sach)) ky dang xay hoi. hieu ((ve pham) or (ke phan)) duc va dinh van cua te".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te sach)) ky dang xay hoi. hieu ((ve pham) or (ke phan)) duc va dinh van cua te*.
