Elastica specification

This library allows you to create Elastica queries using the specification pattern.

Usage

You can write specifications using gbprod/specification library.

Creates a elastica specification filter

namespace GBProd\Acme\Elastica\SpecificationFactory;

use GBProd\ElasticaSpecification\QueryFactory\Factory;
use GBProd\Specification\Specification;
use Elastica\QueryBuilder;

class IsAvailableFactory implements Factory
{
    public function create(Specification $spec, QueryBuilder $qb)
    {
        return $qb->query()->bool()
            ->addMust(
                $qb->query()->term(['available' => "0"]),
            )
        ;
    }
}

Configure

$registry = new GBProd\ElasticaSpecification\Registry();
$qb = new \Elastica\QueryBuilder();

$handler = new GBProd\ElasticaSpecification\Handler($registry, $qb);
$handler->registerFactory(IsAvailable::class, new IsAvailableFactory());
$handler->registerFactory(StockGreaterThan::class, new StockGreaterThanFactory());

Use it

$available = new IsAvailable();
$hightStock = new StockGreaterThan(4);

$availableWithLowStock = $available
    ->andX(
        $hightStock->not()
    )
;

$type = $this->elasticaClient
    ->getIndex('my_index')
    ->getType('my_type')
;

$query = $handler->handle($availableWithLowStock)

$results = $type->search($query);
