I was wondering can one search for a pattern of ordered keywords? For
example, search for:
bob book alice
returns two different documents containing sentences:
bob quickly gives the book to alice
alice gently gives the book to olivia and bob
If order matters, the correct match should be the first one only. Google for
example, solves this problem with a phrase search:
"bob * book * alice"
Is it possible to implement something similar by using Lucy?
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 );

Thank you Marvin.
It would be nice to have something like Google's phrase search: "here's
looking * * kid"
Have a look at Search::Query with the Lucy dialect.
my $query_parser = Search::Query->parser(
query_class => 'Lucy',
query_class_opts => {
ignore_order_in_proximity => 0, # the default
},
default_field => 'content',
);
my $string = qq/"here's looking * * kid"~10/; # proximity within => 10
my $query = $query_parser->parse($string);
my $lucy_query = $query->as_lucy_query();
my $hits = $lucy_searcher->hits( query => $lucy_query );
