Maybe LucyX::Search::ProximityQuery with a high value for "within"?
my $analyzer = $searcher->get_schema->fetch_analyzer("content");
my $terms = $analyzer->split("bob book alice");
my $proximity_query = LucyX::Search::ProximityQuery->new(
field => 'content',
terms => $terms,
within => 1000, # match within 1000 positions
);
my $hits = $searcher->hits( query => $proximity_query );
