PostgreSearchBundle
Symfony2 bundle with tools full-text search PostgreSQL in Doctrine 2., (*1)
Added type 'tsvector' to be used in the mapping., (*2)
Added functions 'to_tsquery', 'plainto_tsquery' and 'ts_rank' to be used in the DQL., (*3)
Step 1: Download PostgreSearchBundle using composer
Add PostgreSearchBundle in your composer.json:, (*4)
{
    "require": {
        "intaro/postgres-search-bundle": "dev-master"
    }
}
Now tell composer to download the bundle by running the command:, (*5)
``` bash
$ php composer.phar update intaro/postgres-search-bundle, (*6)
### Step 2: Enable the bundle
Enable the bundle in the kernel:
``` php
<?php
// app/AppKernel.php
public function registerBundles()
{
    $bundles = array(
        // ...
        new Intaro\PostgresSearchBundle\IntaroPostgresSearchBundle(),
    );
}
Step 3: Mapping example
/**
 * @var string
 *
 * @ORM\Column(name="search_fts", type="tsvector", options={"customSchemaOptions": {"searchFields":{"name", "genre"}}}, nullable=true)
 */
protected $searchFts;
Step 4: Use in DQL
$searchQuery = 'family | history';
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
    'SELECT b.id, sum(TSRANK(b.searchFts, :searchQuery)) as rank
        FROM DemoSearchBundle:Books b
        WHERE TSQUERY( b.searchFts, :searchQuery, \'simple\' ) = true
        GROUP BY b.id
        ORDER BY rank DESC')
    ->setParameter('searchQuery', $searchQuery)
;
$result = $query->getArrayResult();
Result example:, (*7)
Array
(
    [0] => Array
        (
            [id] => 2
            [rank] => 0.0607927
        )
    [1] => Array
        (
            [id] => 3
            [rank] => 0.0303964
        )
