Maybe someone who really knows the mail app can tell us how mail search is supposed to work.
If I have a mail box labeled "Overall" and 5 sub mailboxes to that labeled, "one", "two", "three", "four", and "five" and I search "Overall" does the search include the sub-mailboxes (one, two, three, four, five) and give you results from all of them or just "Overall" and only at that level of "Overall." This means you would have to go directly to "One" or "Three" etc., to search them for content.
That is how my mail searches now. I cannot get search results for a whole mailbox and its sub mailboxes but only for one mailbox at a time. I can search All Mailboxes though. And Inbox too. I could have sworn back a while ago you could get search results for a mailbox and all it sub-mailboxes at once.
Is this how it is now? You can't only search one specific mailbox at a time?
Thank you whoever knows the answer.
