• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((((ty lang) OR (ty hang))) OR (ty xang)) xa hoi. hieu ve nuoc luc va thanh pho cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((((ty lang) OR (ty hang))) or (ty xang)) xa hoi. hieu ve nuoc luc va thanh pho cua te~".
• Adding a wildcard symbol may retrieve word variants: vu sach ((((ty lang) OR (ty hang))) or (ty xang)) xa hoi. hieu ve nuoc luc va thanh pho cua te*.
