• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((((chieu sang) OR (nhieu tang))) OR (hieu lang)) - anh quang tran hung cong ty toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((((chieu sang) OR (nhieu tang))) or (hieu lang)) - anh quang tran hung cong ty toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((((chieu sang) OR (nhieu tang))) or (hieu lang)) - anh quang tran hung cong ty toan cau*.
