Google Cloud Search

Google Cloud Search is an enterprise search tool integrated with Google Workspace. It allows users to search for content in Google apps including Gmail, Google Docs, Google Drive, Google Calendar, Google Contacts, and Google Sites. It also provides “actionable information & recommendations” to users based on machine learning.
In February 2017, Google Springboard was renamed Google Cloud Search.

Release

At the time of launch, Google had its Springboard broadly at an "Invite-only" access and at the moment, it has closed the applications towards its Early Adopter Program.
