Subject: [PATCH 22/36] lib/query: factor out _notmuch_query_string_to_xapian_query
Date: Tue, 24 Aug 2021 08:17:31 -0700	[thread overview]
Message-ID: <20210824151745.2941868-23-david@tethera.net> (raw)
In-Reply-To: <20210824151745.2941868-1-david@tethera.net>

When dealing with recursive queries (i.e. thread:{foo}) it turns out
to be useful just to deal with the underlying Xapian objects, and not
wrap them in notmuch objects.
