SearchView will set it to `undef', others will set the 'mset'
option (for the ->mset method :P) to 2 which causes {relevance}
to be ignored.
And the 'mset' option is poorly named now that the message
is named ->mset...
$opts ||= {};
my $qp = $self->{qp} //= qparse_new($self);
my $query = $qp->parse_query($query_string, $self->{qp_flags});
- $opts->{relevance} = 1 unless exists $opts->{relevance};
_do_enquire($self, $query, $opts);
}
