• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - hanh trang cua ((nhung cong) OR (thong cong)) dan than tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hanh trang cua ((nhung cong) or (thong cong)) dan than tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hanh trang cua ((nhung cong) or (thong cong)) dan than tap*.
