NAME

Lucy::Search::MatchAllQuery - Query which matches all documents.

DESCRIPTION

MatchAllQuery is a utility class which matches all documents. Each match is assigned a score of 0.0, so that in composite queries, any document which matches against another part of the query will be ranked higher than a document which matches only via the MatchAllQuery.

CONSTRUCTORS

new

my $match_all_query = Lucy::Search::MatchAllQuery->new;

Constructor. Takes no arguments.

METHODS

make_compiler

my $compiler = $match_all_query->make_compiler(
    searcher    => $searcher,     # required
    boost       => $boost,        # required
    subordinate => $subordinate,  # default: false
);

Abstract factory method returning a Compiler derived from this Query.

  • searcher - A Searcher.

  • boost - A scoring multiplier.

  • subordinate - Indicates whether the Query is a subquery (as opposed to a top-level query). If false, the implementation must invoke normalize() on the newly minted Compiler object before returning it.
