Changes to Code Search Indexing

Starting today, GitHub Code Search will only index repositories that have had recent activity within the last year. Recent activity for a repository means that it has had a commit or has shown up in a search result. If the repository does not have any activity for an entire year, the repository will be purged from the Code Search index. This change will enable the most relevant content for developers to surface in the code search index as well as keeping code search queries fast for all customers.
