a reference to the parent :class:`Query` object. Otherwise
the Query() would be immediately freed, taking our *msgs*

automatically freed whenever we delete all derived objects,

Query (but not the parent Database() as that is still

Welcome to :mod:`cnotmuch`'s documentation
===========================================
The :mod:`cnotmuch` module provides an interface to the `notmuch <http://notmuchmail.org>`_ functionality, directly interfacing to a shared notmuch library.
The classes :class:`Database`, :class:`Query` provide most of the core functionality, returning :class:`Messages` and :class:`Tags`.
