NAME ^

REST::Neo4p::Index - Neo4j index object

SYNOPSIS ^

 $node_idx = REST::Neo4p::Index('node', 'my_node_index');
 $rel_idx = REST::Neo4p::Index('relationship', 'my_rel_index');
 $fulltext_idx = REST::Neo4p::Index('node', "my_ft_index,
                                    { type = 'fulltext',
                                      provider = 'lucene' });
 $node_idx->add_entry( $ShaggyNode, 'pet' => 'ScoobyDoo' );
 @returned_nodes = $node_idx->find_entries('pet' => 'ScoobyDoo');
 @returned_nodes = $node_idx->find_entries('pet:Scoob*');
 $node_idx->remove_entry( $JosieNode, 'hair' => 'red' );

DESCRIPTION ^

REST::Neo4p::Index objects represent Neo4j node and relationship indexes.

METHODS ^

new()
 $node_idx = REST::Neo4p::Index('node', 'my_node_index');
 $rel_idx = REST::Neo4p::Index('relationship', 'my_rel_index');
 $fulltext_idx = REST::Neo4p::Index('node', "my_ft_index,
                                    { type = 'fulltext',
                                      provider = 'lucene' });

Creates a new index of the type given in the first argument, with the name given in the second argument. The optional third argument is a hashref containing an index configuration as provided for in the Neo4j API.

remove()
 $index->remove()
name()
 $idx_name = $index->name()
type()
 if ($index->type eq 'node') { $index->add_entry( $node, $key ); }
add_entry()
 $index->add_entry( $node, $key => $value );
remove_entry()
 $index->remove_entry($node);
 $index->remove_entry($node, $key);
 $index->remove_entry($node, $key => $value);
find_entries()
 @returned_nodes = $node_index->find_entries($key => $value);
 @returned_rels = $rel_index->find_entries('pet:Scoob*');

In the first form, an exact match is sought. In the second (i.e., when a single string argument is passed), the argument is interpreted as a query string and passed to the index as such. The Neo4j default is Lucene.

find_entries() is not supported in batch mode.
