• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty hang) OR (ty xang)) xa hoi. hieu van cau luc van anh ((vi cau) OR (ve cau)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty hang) or (ty xang)) xa hoi. hieu van cau luc van anh ((vi cau) OR (ve cau)) tren".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty hang) or (ty xang)) xa hoi. hieu van cau luc van anh ((vi cau) OR (ve cau)) tren*.
