Correct. All four of those forms are giving you phrase searches, (so a
term "org" followed immediately by a term "notmuch").

No, I don't think you are seeing a match on the mailing-list address
itself, (which has "notmuch" two terms before "org").

David showed you one example from the message you copied:

And I showed one earlier in the thread.

In each case, the message includes "org" followed (after some amount of
punctuation and whitespace, perhaps including newlines) by "notmuch".
