public buildScore ( GraphAware\Common\Type\Node $input, GraphAware\Common\Type\Node $item, GraphAware\Common\Result\Record $record, GraphAware\Reco4PHP\Context\Context $context ) : SingleScore
$input	GraphAware\Common\Type\Node
$item	GraphAware\Common\Type\Node
$record	GraphAware\Common\Result\Record
$context	GraphAware\Reco4PHP\Context\Context
Résultat	GraphAware\Reco4PHP\Result\SingleScore	A single score produced for the recommended item

public defaultScore ( ) : float
Résultat	float	The default score to be given to the discovered recommended item

The statement to be executed for finding items to be recommended.

public discoveryQuery ( GraphAware\Common\Type\Node $input, GraphAware\Reco4PHP\Context\Context $context ) : GraphAware\Common\Cypher\StatementInterface
$input	GraphAware\Common\Type\Node
$context	GraphAware\Reco4PHP\Context\Context
Résultat	GraphAware\Common\Cypher\StatementInterface

public name ( ) : string
Résultat	string	The name of the discovery engine

Returns a collection of Recommendation object produced by this discovery engine.

public produceRecommendations ( GraphAware\Common\Type\Node $input, GraphAware\Common\Result\ResultCollection $resultCollection, GraphAware\Reco4PHP\Context\Context $context ) : Recommendations
$input	GraphAware\Common\Type\Node
$resultCollection	GraphAware\Common\Result\ResultCollection
$context	GraphAware\Reco4PHP\Context\Context

public recoResultName ( ) : string
Résultat	string	The column identifier of the row result representing the recommended item (node)

public scoreResultName ( ) : string
Résultat	string	The column identifier of the row result representing the score to be used, note that this is not mandatory to have a score in the result. If empty, the score will be the float value returned by `defaultScore()` or the score logic if the concrete class override the `buildScore` method.
