Github completely redesigned the search

On Wednesday, January 23, Github launched a new, significantly redesigned and improved search for code, repositories, and developers. Now the infrastructure is provided by the ElasticSearch server cluster , which indexes all the added code on the fly, the interface is noticeably redesigned, and, most importantly, there are many functional improvements.
Results of search repositories can be filtered by the number of stars, forks, owner, and size. When searching for a code - by the size and type of file, its location. Users can be filtered by number of subscribers, repositories and by location. To make the results more relevant, the code from the forks is indexed only if the popularity of the fork exceeds the popularity of the parent repository.
The repository search results show the time the latest changes were made. When searching for code, line numbers are visible and syntax is highlighted.
Search results for registered users now include their private repositories.
