Nexis Uni Advanced Search allows you to build a more specific search by providing multiple search boxes, search fields, date ranges, sources, and content types. Change the search field with the drop-down menu to the right of the search box. Select a date range from the drop-down menu. List sources to search within in the "Sources" box. You can also switch from searching "All" content types to searching for "News," "Company and Financial," or "Legal" above the search box.
