Forked from floriansemm/solr-bundle to integrate with Solarium 5, Symfony > 4.3

This Bundle provides a simple API to index and query a Solr Index.

1. Download SolrBundle
2. Enable the Bundle
3. Configure the SolrBundle
4. configure your entity

This bundle is available on Packagist. You can install it using Composer:

$ composer require maxgr0/solr-bundle

When using Symfony Flex, you can skip this step.

Next, enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new FS\SolrBundle\FSSolrBundle(),
    );
}

Finally, configure the bundle:

# app/config/fs_solr.yml
fs_solr:
    endpoints:
        core0:
            schema: http
            host: host
            port: 8983
            path: /
            core: corename
            timeout: 5

Default values will be used for any option left out.

# app/config/fs_solr.yml
fs_solr:
    endpoints:
        core0:
            dsn: http://host:8983/
            core: core0
            timeout: 5

Any values in schema, host, port and path option, will be ignored if you use the dsn option.

To make an entity indexed, you must add some annotations to your entity. Basic configuration requires two annotations: @Solr\Document(), @Solr\Id(). To index data add @Solr\Field() to your properties.

If you want to index documents without any database, then you have to use the same annotations. Make sure you have set a Id or set @Solr\Id(generateId=true).

// ....
use FS\SolrBundle\Doctrine\Annotation as Solr;
    
/**
* @Solr\Document()
* @ORM\Table()
*/
class Post
{
    /**
     * @Solr\Id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
    
    /**
     * @Solr\Field(type="string")
     *
     * @ORM\Column(name="title", type="string", length=255)
     */
    private $title = '';

    /**
     * @Solr\Field(type="string")
     *
     * @ORM\Column(name="text", type="text")
     */
    private $text = '';

   /**
    * @Solr\Field(type="date", getter="format('Y-m-d\TH:i:s.z\Z')")
    *
    * @ORM\Column(name="created_at", type="datetime")
    */
    private $created_at = null;
}

The bundle handles now updates / inserts / deletions for your configured entity.

This annotation denotes that an entity should be indexed as a document. It has several optional properties:

• repository
• index
• indexHandler

If you specify your own repository, the repository must extend the FS\SolrBundle\Repository\Repository class.

/**
 * @Solr\Document(repository="My/Custom/Repository")
 */
class SomeEntity
{
    // ...
}

It is possible to specify a core the document will be indexed in:

/**
 * @Solr\Document(index="core0")
 */
class SomeEntity
{
    // ...
}

By default, all documents will be indexed in the core core0. If your entities/documents have different languages, then you can setup a callback method, which should return the core the entity will be indexed in.

/**
 * @Solr\Document(indexHandler="indexHandler")
 */
class SomeEntity
{
    public function indexHandler()
    {
        if ($this->language == 'en') {
            return 'core0';
        }
    }
}

Each core must be set up in config.yml under endpoints. If you leave the index or indexHandler property empty, then the default core will be used (first one in the endpoints list). To index a document in all cores, use * as index value.

This annotation is required to index an entity. The annotation has no properties. You should add this annotation to the field that will be used as the primary identifier for the entity/document.

class Post
{
    /**
     * @Solr\Id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */

    private $id;
}

Set this option to true and a the bundle will generate a Id for you. Use this option if you have no underlying DB which generates incremental Ids for you.

This annotation should be added to properties that should be indexed. You should specify the type option for the annotation.

Currently, a basic set of types is implemented:

• string(s)
• text(s)
• date(s)
• integer(s)
• float(s)
• double(s)
• long(s)
• boolean(s)

If you have a customized schema.xml than you don't need to setup a field-type.

Solr supports partial updates of fields in an existing document. Supported values are:

• set
• add (multivalue field only, adds a value(s) to a existing list)
• remove (multivalue field only, removes a value(s) from existing list)
• inc (integer field only)

Set this property if you want to index collections with nested Objects.

For more information read the more detailed "How to index relation" guide

In some cases, an entity should not be indexed. For this, you have the SynchronizationFilter annotation to run a filter-callback.

/**
 * // ....
 * @Solr\SynchronizationFilter(callback="shouldBeIndexed")
 */
class SomeEntity
{
    /**
     * @return boolean
    */
    public function shouldBeIndexed()
    {
        // put your logic here
    }
}

The callback property specifies an callable function, which should return a boolean value, specifying whether a concrete entity should be indexed.

Querying the index is done via the solr.client service:

$query = $this->get('solr.client')->createQuery('AcmeDemoBundle:Post');
$query->addSearchTerm('title', 'my title');
$query->addSearchTerm('collection_field', array('value1', 'value2'));

$result = $query->getResult();

or

$posts = $this->get('solr.client')->getRepository('AcmeDemoBundle:Post')->findOneBy(array(
    'title' => 'my title',
    'collection_field' => array('value1', 'value2')
));

The previous examples were only querying the title field. You can also query all fields with a string.

$query = $this->get('solr.client')->createQuery('AcmeDemoBundle:Post');
$query->queryAllFields('my title');

$result = $query->getResult();

If you need more flexiblity in your queries you can define your own query strings:

$query = $this->get('solr.client')->createQuery('AcmeDemoBundle:Post');
$query->setCustomQuery('id:post_* AND (author_s:Name1 OR author_s:Name2)');

$result = $query->getResult();

The query-builder based on https://github.com/minimalcode-org/search Criteria API.

$queryBuilder = $this->get('solr.client')->getQueryBuilder('AcmeDemoBundle:Post');
$result = $queryBuilder
    ->where('author')
        ->is('Name1')
    ->orWhere('author')
        ->is('Name2')
    ->getQuery()
    ->getResult();

To keep your code clean you should move the select-criteria in a repository-class:

class YourRepository extends Repository
{
    public function findAuthor($name1, $name2)
    {
        return $this->getQueryBuilder()
            ->where('author')
                ->is($name1)
            ->orWhere('author')
                ->is($name2)
            ->getQuery()
            ->getResult();
    }
}

HydrationMode tells the bundle how to create an entity from a document.

1. FS\SolrBundle\Doctrine\Hydration\HydrationModes::HYDRATE_INDEX - use only the data from solr
2. FS\SolrBundle\Doctrine\Hydration\HydrationModes::HYDRATE_DOCTRINE - merge the data from solr with the entire doctrine-entity

With a custom query:

$query = $this->get('solr.client')->createQuery('AcmeDemoBundle:Post');
$query->setHydrationMode($mode)

With a custom document-repository you have to set the property $hydrationMode itself:

public function find($id)
{
    $this->hydrationMode = HydrationModes::HYDRATE_INDEX;
    
    return parent::find($id);
}

Your should define your own repository-class to make your custom queries reuseable. How to configure a repository for a document have a look at the annotation section

namespace AppBundle\Search;

use FS\SolrBundle\Repository\Repository;

class ProviderRepository extends Repository
{
    public function findPost($what)
    {
        $query = $this->solr->createQuery('AcmeDemoBundle:Post');
        // some query-magic here

        return $query->getResult();
    }
}

In your repository you have full access to the querybuilder.

Here's all the commands provided by this bundle:

• solr:index:clear - delete all documents in the index
• solr:index:populate - synchronize the db with the index
• solr:schema:show - shows your configured documents

The solr:index:populate command works well for sets up to 300k entities, everthing large makes the command very slow. You can find here some solution how to sync your DB with Solr.

To extend Solarium with your own plugins, create a tagged service:

<tag name="solarium.client.plugin" plugin-name="yourPluginName"/>

To hook into the Solarium events create a common Symfony event-listener:

<tag name="kernel.event_listener" event="solarium.core.preExecuteRequest" method="preExecuteRequest" />

$helper = $this->get('solr.client')->getDocumentHelper();
$id = $helper->getLastInsertDocumentId();
