• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu nang xa hoi. ((hieu ve) OR (lieu va)) cam luc gia thanh ((vi cau) OR (ve cau)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu nang xa hoi. ((hieu ve) or (lieu va)) cam luc gia thanh ((vi cau) OR (ve cau)) treo".
• Adding a wildcard symbol may retrieve word variants: te sach thu nang xa hoi. ((hieu ve) or (lieu va)) cam luc gia thanh ((vi cau) OR (ve cau)) treo*.
