The Search Analytics API now supports Discover and Google News.
The searchType parameter, which previously allowed you to filter API calls to news, video, image, and web, will be renamed to type and will support two additional parameters: discover (for Google Discover) and googleNews (for Google News).
In addition, Regex support will be added to the query and page parameters. Two new operators will be added to existing matching operations: includingRegex and excludingRegex.
