• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - canh ((manh cua) OR (ban cua)) ((dung hoang) OR (dang hoang)) van toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - canh ((manh cua) or (ban cua)) ((dung hoang) OR (dang hoang)) van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - canh ((manh cua) or (ban cua)) ((dung hoang) OR (dang hoang)) van toan cau*.
