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

Solr-Server

Follow the installation instructions in this Tutorial

PHP-Extension

	sudo pecl install -n solr-beta

Bundle

1. Register bundle in AppKernel.php

   # app/AppKernel.php
   
   $bundles = array(
       // ...
       new FS\SolrBundle\FSSolrBundle(),
       // ...
   );
   

2. Add Bundle to autoload

   # app/autoload.php
   
   $loader->registerNamespaces(array(
       // ...
       'FS' => __DIR__.'/../vendor/bundles',
       // ...
   ));
   

You have to setup the connection options

	# app/config/config.yml
	
	fs_solr:
		solr:
			hostname: localhost
			port: 8983
		entity_manager: default 

Multiple connections are planed.

To put an entity to the index, you must add some annotations to your entity:

	// your Entity

	// ....
	use FS\SolrBundle\Doctrine\Annotation as Solr;
	
	/**
	 * 
	 *
	 * @Solr\Document(repository="Full\Qualified\Class\Name")
	 * @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")
		 *
		 * @ORM\Column(name="created_at", type="datetime")
		 */
		private $created_at = null;
	}

If you persist this entity, it will put automaticlly to the index. Update and delete happens automatically too.

To query the index you have to call some services.

	$query = $this->get('solr')->createQuery('AcmeDemoBundle:Post');
	$query->addSearchTerm('title', 'my title');
	$query->addField('id');
	$query->addField('text');
	
	$result = $query->getResult();

The $result array contains all found entities. The solr-service does all mappings from SolrDocument to your entity for you. In this case only the fields id and text will be mapped (addField()), so title and created_at will be empty. If nothing was found $result is empty.

If no field was explict add, all fields will be mapped.

	$query = $this->get('solr')->createQuery('AcmeDemoBundle:Post');
	$query->addSearchTerm('title', 'my title');
	
	$result = $result = $query->getResult();

The pervious examples have queried only the field 'title'. You can also query all fields with a string.

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

To index your entities manually, you can do it the following way:

	$this->get('solr')->addDocument($entity);
	$this->get('solr')->updateDocument($entity);
	$this->get('solr')->deleteDocument($entity);

The delete action needs the id of the entity.

If you specify your own repository you must extend the FS\SolrBundle\Repository\Repository class. The useage is the same like Doctrine-Repositories:

$myRepository = $this->get('solr')->getRepository('AcmeDemoBundle:Post');
$result = $myRepository->mySpecialFindMethod();

If you haven't declared a concrete repository in your entity and you calling $this->get('solr')->getRepository('AcmeDemoBundle:Post'), you will get an instance of FS\SolrBundle\Repository\Repository.

There are comming two commands with this bundle:

• solr:index:clear - delete all documents in the index
• solr:synchronize - synchronize the db with the index. You have to specify an entity.
