• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - lanh ((manh cua) OR (ban cua)) khong thuong van phan dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu sang)) - lanh ((manh cua) OR (ban cua)) khong thuong van phan dau*".
