• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (nang ma)) hoi. hieu ve coc luc va ((thanh vi) OR (thanh va)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) OR (nang ma)) hoi. hieu ve coc luc va ((thanh vi) or (thanh va)) cau treo".
