2017 - G Suite gets smart cloud search to defeate Zimbra


Google launched for its business customers a new tool called Google Cloud Search, which will allow users to search across G Suite products, including Drive, Gmail, Sites, Calendar, Docs, Contacts and more. It's designed for use in larger companies where different groups and individuals have access to different files. The search service respects file-sharing permissions, so users can only access what’s available to them, whether that’s company-wide resources like a policy manual, team projects or documents only they can see. In addition to surfacing work documents, Cloud Search works as a directory service, allowing users to seek out colleagues’ contact information, while also viewing the events and files they have in common. When viewing a contact’s info in the search results, users are able to click to start an email, phone call or a Hangout.
