This package makes it simple to index large amounts of data to Solr.

Installation

You can include this package through Composer using:

composer require tubber/model-indexer

Usage

Indexing documents

To be able to index any documents, you first need a class that implements the IndexableInterface:

use Solarium\QueryType\Update\Query\Document;

class IndexableModel implements \Tubber\Indexer\Contracts\IndexableInterface
{

    /**
     * Get an array of documents that need to be indexed for this object
     *
     * @return array|Document[]
     */
    public function indexingDocuments(): array
    {
        return [
            new Document([
                'id' => 1,
                'name' => 'document 1'
            ]),
            new Document([
                'id' => 2,
                'name' => 'document 2'
            ]),
        ];
    }

    /**
     * Mark this object as indexed
     *
     * @return void
     */
    public function markAsIndexed(): void
    {
        return; // Perform some kind of action to indicate this object has been indexed
    }
    
    /**
     * Get the query to delete this object from the given core
     *
     * @param string $search_core
     * @return string
     */
    public function getDeleteQueryFor(string $search_core): string
    {
        return "id: 1";
    }
}

This class is now ready to be indexed. However, you will also need to provide the ModelIndexer with some kind of configuration, so it knows where to send your documents. All you need to do is create a new class that implements SolrConfigInterface:

use Solarium\Client;
use Tubber\Indexer\Contracts\SolrConfigInterface;

class SearchConfig implements SolrConfigInterface
{

    /**
     * Get the client for this Solr interaction
     *
     * @return Client
     */
    public function getClient(): Client
    {
        $client = new Client();

        $client
            ->getEndpoint('your_solarium_endpoint_name')
            ->setCore('your_core_name');

        return $client;
    }

    /**
     * Reload the core that's provided in $this->getClient
     *
     * @return void
     */
    public function reloadCollection(): void
    {
        // You can implement your own way of reloading the collection
        // This method is call after indexing has finished
    }
}

Now you can index your documents by running the ModelIndexer perform() method:


/**@var array|Document[] $documents*/
$documents = [
    new IndexableModel()
];

ModelIndexer::forModels($documents, new SearchConfig)->perform();

Removing documents

You can remove documents by using the ModelRemover class. The invocation is identical to ModelIndexer:

use Tubber\Indexer\ModelRemover;

ModelRemover::forModels($documents, new SearchConfig)->perform();

You need to specify the delete query in the getDeleteQueryFor method on your classes that implement IndexableInterface. The search core name is passed to the method, in case you're indexing that class into multiple cores.

Available methods

To start using the ModelIndexer class, you have to call forModels().

/**
 * Set the collection of models that need to be indexed
 *
 * @param array $models
 * @param SolrConfigInterface $config
 * @return ModelIndexer
 * @throws NoCoreFoundException
 */
public static function forModels(array $models, SolrConfigInterface $config): ModelIndexer;

You can customize the buffer size and the commit within value:

public function setBufferSize(int $buffer_size = 100): ModelIndexer;

and

public function setCommitWithin(int $commit_within = 10000): ModelIndexer;

These methods are fluent setters, so you can chain them:

ModelIndexer::forModels($models, new SearchConfig)
    ->setBufferSize(1500)
    ->setCommitWithin(5000)
    ->perform();

You can index the documents by calling the perform() method.

/**
 * Perform the indexing for the models in this class
 *
 * @throws \InvalidArgumentException
 */
public function perform(): void;

Testing

You can run the included tests by running ./vendor/bin/phpunit in your terminal.

You can’t perform that action at this time.
