Issue Summary:

On July 2, 2019 at 1:44 p.m. PDT searches began to fail for a subset of users. After some investigation, the root cause was traced to a set of very large messages causing the search indexing feature to become overloaded and fail. We suspended these specific messages from being indexed and implemented a message-index size limit. This allowed systems to return back to normal by July 4, 2019 at 12:07 a.m. PDT.
