NAME

6       Lucy::Search::LeafQuery - Leaf node in a tree created by QueryParser.
7

SYNOPSIS

9           package MyQueryParser;
10           use base qw( Lucy::Search::QueryParser );
11
12           sub expand_leaf {
13               my ( $self, $leaf_query ) = @_;
14               if ( $leaf_query->get_text =~ /.\*\s*$/ ) {
15                   return PrefixQuery->new(
16                       query_string => $leaf_query->get_text,
17                       field        => $leaf_query->get_field,
18                   );
19               }
20               else {
21                   return $self->SUPER::expand_leaf($leaf_query);
22               }
23           }
24

DESCRIPTION

26       LeafQuery objects serve as leaf nodes in the tree structure generated
27       by QueryParser’s tree() method.  Ultimately, they must be transformed,
28       typically into either TermQuery or PhraseQuery objects, as attempting
29       to search a LeafQuery causes an error.

CONSTRUCTORS

32   new
33           my $leaf_query = Lucy::Search::LeafQuery->new(
34               text  => '"three blind mice"',    # required
35               field => 'content',               # default: undef
36           );
37
38       Create a new LeafQuery.
39
40       •   field - Optional field name.
41
42       •   text - Raw query text.

56           my $compiler = $leaf_query->make_compiler(
57               searcher    => $searcher,     # required
58               boost       => $boost,        # required
