Your comment doesn't make much sense, to me. It's obvious that they've thought about adding search to their client. What about it not being in, at launch, makes you think that it'll be slow? Why is it not worth discussing the mail client? We have a basic web app that we built at work that stores information about tasks that our automated applications perform, so that we can monitor them as they run. We added full text search to it almost six months after building it, and search was a complete after-thought. We chose elastic search and store about 12 million records in a small cluster. We add maybe several thousand per day, on a busy day. This is not a large amount of records, from what I've seen of other clusters. We easily average less than 200ms response times of search queries across all documents, while testing it with about 100 queries per second. I don't know whether or not you consider this fast or slow, but it's pretty snappy, in my opinion. So search doesn't seem all that mystical and complicated to me, but maybe our scenario just makes it appear that way.
