Apparently, terms with a common prefix are *not* connected by implicit "OR"

Thanks for the report. As a test, can you try with

     $ notmuch count '(to:pontodosconcursos.com.br to:"jorge+cp+concurso at disroot.org")'

I suspect that will work around the problem, which I believe is related
to the way that notmuch uses the xapian parser (in order to provide
regexp matching for some prefixes). In particular, if I try that with
NOTMUCH_DEBUG_QUERY=yes in the environment I can see the implicit OR.
