But is it right? Bug 24117 has a different submitter.
It is correct. Your search is not related to the *submitter*
'dgutov@yandex.ru', but to the *author*.
Your search returns bugs, which
- contain a message with the word 'url-retrieve-synchronously', AND
- have the author 'dgutov@yandex.ru' of this message.
This is how the debbugs search works. It is message oriented, and not
bug oriented. The presentation as a bug is a convenient layer of
debbugs-gnu.el. Maybe it could also highlight the respective message(s)
in the gnus/rmail summary, but this is not implemented.
