• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((xu lang) OR (tu lanh)) xa hoi. hieu va dao duc va ((thanh phan) OR (thanh san)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((xu lang) or (tu lanh)) xa hoi. hieu va dao duc va ((thanh phan) OR (thanh san)) cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ((xu lang) or (tu lanh)) xa hoi. hieu va dao duc va ((thanh phan) OR (thanh san)) cua te*.
