Installation

Install the bundle:

$ composer require nzo/elastic-query-bundle

Register the bundle in config/bundles.php (without Flex)

// config/bundles.php

return [
    // ...
    Nzo\ElasticQueryBundle\ElasticQueryBundle::class => ['all' => true],
];

Configure the bundle:

# config/packages/nzo_elastic_query.yaml

nzo_elastic_query:
    elastic_index_prefix:  # optional (the index prefix)
    default_page_number:   # optional (default 1)
    limit_per_page:        # optional (default 100)
    items_max_limit:       # optional (default 1000)
    show_score:            # optional (default false)
    

Usage

use Nzo\ElasticQueryBundle\Query\ElasticQuerySearch;

class MyClass
{
    /**
     * @var ElasticQuerySearch
     */
    private $elasticQuerySearch;
    
    public function __construct(ElasticQuerySearch $elasticQuerySearch)
    {
        $this->elasticQuerySearch = $elasticQuerySearch;
    }
    
    /**
     * @param string|array $query  (json or array)
     * @param string $entityNamespace The FQCN (fully qualified class name) of the entity to execute the search on.
     * @param null|int $page
     * @param null|int $limit
     * @return array
     */
    public funtion foo($query, $entityNamespace, $page = null, $limit = null)
    {
        // $entityNamespace === 'App\Entity\FooBar'
        
        return $this->elasticQuerySearch->search($query, $entityNamespace, $page, $limit);
        
        // check access permission on the search
        return $this->elasticQuerySearch->search(
            $query,
            $entityNamespace,
            $page,
            $limit,
            ['role' => 'ROLE_SEARCH', 'message' => 'Search not authorized'] // 'message' is optional
        );
    }
}

When show_score is enabled, you must add the field _scoreElastic to the needed entities and add the field getter and setter (getScoreElastic & setScoreElastic)

    private float $_scoreElastic;

    public function getScoreElastic(): float
    {
        return $this->_scoreElastic;
    }

    public function setScoreElastic(float $scoreElastic): self
    {
        $this->_scoreElastic = $scoreElastic;

        return $this;
    }

Configure index

fos_elastica:
    indexes:
        user:
            properties:
                id:
                    type: keyword
                    index: true
                createdAt:
                    type:   date
            persistence:
                driver: orm
                model: App\Entity\User
                provider: ~
                finder: ~
                repository: Nzo\ElasticQueryBundle\Repository\SearchRepository

Populate index

$ bin/console fos:elastica:populate
