DoctrineSolrBundle

, _(*1)

DoctrineSolrBundle is a Symfony bundle designed to mitigate Solr usage in symfony projects, _(*2)

Features

Auto-indexing doctrine entities in Solr
Supports wildcard, fuzzy & negative searches by specific entity fields
Supports Range searches by specific entity fields
Supports Boosting a Term by specific entity fields
Supports Solr SuggestComponent
Supports filters by entity fields or custom symfony service before indexing
Auto-resolving search results in Doctrine entities
Supports implementation of separate finder class for particular entity class
Flexible query building interface
Cross-search over different entity classes

Installation

Step 1 Download DoctrineSolrBundle using composer

$ composer require mdiyakov/doctrine-solr-bundle

Composer will install the bundle to your project's vendor/mdiyakov/doctrine-solr-bundle directory., _(*3)

Step 2

Enable the bundle in the kernel :, _(*4)

// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Nelmio\SolariumBundle\NelmioSolariumBundle(),
        new Mdiyakov\DoctrineSolrBundle\MdiyakovDoctrineSolrBundle(),
        // ...
    );
}

You have to install "NelmioSolariumBundle" also because it's used by MdiyakovDoctrineSolrBundle, _(*5)

Step 3 : Quick start with DoctrineSolrBundle

Prerequisites

Solr schema.yml created and solr core is initialized
Solr schema.yml unique field is "uid"
Solr schema.yml consists "document_id", "document_title" and "discriminator" fields
AppBundle\Entity\MyEntity is created and has "id" and "title" fields

DoctrineSolrBundle is using "NelmioSolariumBundle" for solarium integration. So you need to set a configuration to use it. Here is minimum config:, _(*6)

nelmio_solarium: ~

The default solr endpoint will be used in this case (http://localhost:8983/solr), _(*7)

Init bundle configuration in config.yml. Quick example:, _(*8)

 mdiyakov_doctrine_solr:
    indexed_entities:
        my_entity:
            class: AppBundle\Entity\MyEntity
            schema: my_schema
            config:
                - { name: config_field_name, value: config_field_value }
    schemes:
        my_schema:
            document_unique_field: { name: 'uid' }
            config_entity_fields:
                - {  config_field_name: 'config_field_name', document_field_name: 'discriminator', discriminator: true }
            fields:
                - {  entity_field_name: 'id', document_field_name: 'document_id', field_type: int, entity_primary_key: true }
                - {  entity_field_name: 'title', document_field_name: 'document_title', suggester: 'title' }

As a result "id" and "title" fields of "AppBundle\Entity\MyEntity" will be synced with Solr each time "AppBundle\Entity\MyEntity" is created, updated or removed., _(*9)

If you use doctrine/orm < 2.5 then you have to add an annotation to "AppBundle\Entity\MyEntity" class:, _(*10)

@ORM\EntityListeners({"Mdiyakov\DoctrineSolrBundle\EventListener\DoctrineEntityListener"})

To search "AppBundle\Entity\MyEntity" use the following code:, _(*11)

// MyController
//...
// @var \Mdiyakov\DoctrineSolrBundle\Finder\ClassFinder $finder 
$finder = $this->get('ds.finder')->getClassFinder(MyEntity::class);

/** @var MyEntity[] $searchResults */
$searchResults = $finder->findSearchTermByFields($searchTerm, ['title']);
//...
