Replying to myself so that the solution is saved in the archives. In
0.15, this issue can be solved using QueryParser:

my $title_parser = KinoSearch::QueryParser::QueryParser->new(
    analyzer       => $analyzer,
    fields         => ['title'],
    default_boolop => 'AND',
);
my $by_title = $tag_parser->parse('organic');
$bool_query->add_clause(query => $by_title, occur => 'MUST');
