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": {
        "alsatian/postgres-search-bundle": "dev-master"
    }
}

Enable the bundle in the kernel:

``` php
<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Alsatian\PostgresSearchBundle\AlsatianPostgresSearchBundle(),
    );
}

 *
 * @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();
