You've used a ManyToMany field, so there isn't a "particular question"
associated with a Search - there are Many, hence the name. So which of
the many questions are you hoping to get?
You can get *all* of them by simply doing:
search.questions.all()
which returns a queryset, ie a list-like object containing several
questions. See the documentation here:
