Hi :)

so I found a weird bug with notmuch_query_add_tag_exclude.  Apparently,
when I exclude 'spam', and search for 'spam', I still get results, but
if I exclude 'spam', and search for 'is_a_spam', I get no results, even
though there are mails tagged with that tag.

~~~ snip ~~~
import notmuch

d = notmuch.Database()
q = d.create_query("tag:spam")
q.exclude_tag("spam")
assert len(list(q.search_messages())) > 0

q = d.create_query("tag:is_a_spam")
assert len(list(q.search_messages())) > 0

q = d.create_query("tag:is_a_spam")
q.exclude_tag("spam")
assert len(list(q.search_messages())) > 0, "weird"
~~~ snip ~~~

% python3 ignore_tag_bug.py
Traceback (most recent call last):
  File "ignore_tag_bug.py", line 13, in <module>
    assert len(list(q.search_messages())) > 0, "weird"
AssertionError: weird
% notmuch --version
notmuch 0.26

Cheers,
Justus

I'm not sure I follow you you. Can you try with

    export NOTMUCH_DEBUG_QUERY=yes

and see what the query terms are?

The latter actually sounds legit assuming

    - the excluded messages are tagged spam
    - the query parser is not breaking is_a_spam up, but treating it as
      one term.

Uh, actually they are, so there is no bug other than me being
confused...

Sorry for the noise...
