NAME

LucyX::Search::AnyTermQuery - Lucy query extension for not NULL values

SYNOPSIS

 my $query = LucyX::Search::AnyTermQuery->new(
    field   => 'color',
 );
 my $hits = $searcher->hits( query => $query );
 # $hits == documents where the 'color' field is not empty

DESCRIPTION

LucyX::Search::AnyTermQuery extends the Lucy::QueryParser syntax to support NULL values.

METHODS

This class is a subclass of Lucy::Search::Query. Only new or overridden methods are documented here.

new( args )

Create a new AnyTermQuery object. args must contain key/value pair for field.

get_field

Retrieve the value set in new().

equals

Returns true (1) if the object represents the same kind of query clause as another AnyTermQuery.

NOTE: Currently a AnyTermQuery and a NullTermQuery object will evaluate as equal if they have the same field. This is a bug.

to_string

Returns the query clause the object represents.

make_compiler

Returns a LucyX::Search::NullCompiler object.
