I found this article last August when I encountered the M365 eDiscovery search error I recently announced. It is out of date on a couple points, but it has been sitting in my News list because Bruce does a very good job of putting Microsoft Search evolution in context. It is unlikely that the eDiscovery service issue I found contributed to Bruce’s erratic search results. Microsoft’s monumental challenge of universal enterprise search combined with their rapid cloud dev cycles is likely the culprit. They know what needs to happen, but Microsoft is effectively performing rocket surgery while launching enterprises into the clouds. Too many moving parts. Too much data. Teams rapid adoption is complicating a complex situation. I have spent far too much time delving into Teams architecture from a forensic/discovery perspective. It will pose even greater challenges than OneDrive search.
