I use Outlook, Gmail and Mail on a daily basis on a wide range of devices as mail clients. Mail clients are used for three things in my life, to send mail, to read mail and to look up old mails to answer questions. The first two can be managed in all mail clients I have used but the problem often become visible when we look at the third. I have yet to find a single mail client that can provide me a search which gives me the answer I want in the first search. What would the perfect search look like you might ask?
