Overview

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

Constructors

    my $leaf_query = Lucy::Search::LeafQuery->new(
        text  => '"three blind mice"',    # required
        field => 'content',               # default: undef
    );

`•`	`field` - Optional field name.
