NAME

Search::Query::Clause - part of a Dialect

SYNOPSIS

my $clause = Search::Query::Clause->new(
   field => 'color',
   op    => '=',
   value => 'green',
);
my $query = Search::Query->parser->parse("color=red");
$query->add_or_clause( $clause );
print $query; # +color=red color=green

DESCRIPTION

A Clause object represents a leaf in a Query Dialect tree.

METHODS

field

op

value

quote

proximity

is_tree

Returns true if the Clause has child Clauses.

has_children

Returns the number of child Clauses if is_tree() is true.

Returns undef if is_tree() is false.

stringify

Returns Clause as a string. Like Dialect, string-like operators are overloaded to call stringify().

NOTE that stringify() is not necessarily called by the parent Dialect object when the Dialect object is stringifying itself.
