I don't think the issue with your test is the same problem. With that
sample data, 'from:"Search By From Name"' works fine to match the
thread. I'm not really sure why your test is failing, but in general it
doesn't really make sense to search for punctuation, unless you use a
(slower) regexp search. The details are in notmuch-search-terms(7),
under "Terms and phrases"

Can you provide a sample complete message where searching doesn't work?
I suspect it's most likely a problem with the encoded header. I tried
copying your "Shedhalle" from header into a test message and it seemed
like the terms for phrase search were not being generated at index
time. That looks like a bug, but I'd prefer to see a real message, if
