PostgreSearchBundle

Symfony2 bundle with tools full-text search PostgreSQL in Doctrine 2.

Added type 'tsvector' to be used in the mapping.

Added functions 'to_tsquery', 'plainto_tsquery' and 'ts_rank' to be used in the DQL.

Step 1: Download PostgreSearchBundle using composer

Add PostgreSearchBundle in your composer.json:

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

Now tell composer to download the bundle by running the command:

$ php composer.phar update alsatian/postgres-search-bundle

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php
// app/AppKernel.php

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

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:

Array
(
    [0] => Array
        (
            [id] => 2
            [rank] => 0.0607927
        )
    [1] => Array
        (
            [id] => 3
            [rank] => 0.0303964
        )
)
