NAME

Search::Query::Dialect - query dialect base class

SYNOPSIS

 my $query = Search::Query->parser->parse('foo');
 print $query;

DESCRIPTION

Search::Query::Dialect is the base class from which all query dialects inherit.

A Dialect subclass must implement at least two methods:

stringify

Returns the serialized query tree.

stringify_clause( leaf )

Returns one clause of a serialized query tree.

See Search::Query::Dialect::Native for a working example.

METHODS

This class is a subclass of Rose::ObjectX::CAF. Only new or overridden methods are documented here.

stringify

All subclasses must override this method. The default behavior is to croak.

tree

Returns the query Dialect instance as a hashref structure, similar to that of Search::QueryParser.

walk( CODE )

Traverse a Dialect object, calling CODE on each Clause. The CODE reference should expect 4 arguments:

  • The Clause object.

  • The Dialect object.

  • The CODE reference.

  • The prefix ("+", "-", and "") for the Clause.

add_or_clause( clause )

Add clause as an "or" leaf to the Dialect object.

add_and_clause( clause )

Add clause as an "and" leaf to the Dialect object.

add_not_clause( clause )

Add clause as a "not" leaf to the Dialect object.
