• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((va nang) OR (van nang)) xa hoi. hieu ve cham ((soc va) OR (luc va)) danh dien cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((va nang) OR (van nang)) xa hoi. hieu ve cham ((soc va) or (luc va)) danh dien cua te".
