• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) hang va hoi. ((hieu ve) OR (lieu va)) cam duc gia thanh vien cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach tu)) hang va hoi. ((hieu ve) or (lieu va)) cam duc gia thanh vien cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach tu)) hang va hoi. ((hieu ve) or (lieu va)) cam duc gia thanh vien cuu tre*.
