• If you are trying to use Boolean operators, they must be ALL CAPS: tu anh thuc ((hoang dai) OR (hoang da)) hoi. hieu vien ((cac tuc) OR (cac tu)) va danh di hoa viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu anh thuc ((hoang dai) OR (hoang da)) hoi. hieu vien ((cac tuc) or (cac tu)) va danh di hoa viet~".
• Adding a wildcard symbol may retrieve word variants: tu anh thuc ((hoang dai) OR (hoang da)) hoi. hieu vien ((cac tuc) or (cac tu)) va danh di hoa viet*.
