Back-Office Search Synonyms 

The back-office Elasticsearch engine supports configurable search synonyms, so abbreviated and spelled-out forms resolve to the same matches (for example, 123 Main St ≡ 123 Main Street, 118 NE Dr ≡ 118 Northeast Drive, NC ≡ North Carolina).

This is a config-driven, developer-facing capability and there is no synonyms management UI in the back-office. Synonym groups are stored as Oro\Bundle\ElasticSearchBundle\Entity\Synonym reference data (one Solr synonym group per row) and are usually seeded via a data migration.

Enabling Synonyms for Entity Index 

  1. Mark the entity as synonym-aware in its Resources/config/oro/search.yml:

    search:
    Acme\Bundle\AcmeBundle\Entity\MyEntity:
        alias: acme_my_entity
        synonyms_enabled: true
        # ... fields

2. Enable the Enable Search Synonyms option under System Configuration > General Setup > Search > Search Synonyms in the back-office (oro_elastic_search.synonyms_enabled). Toggling it applies synonyms live, no full reindex is required.

  1. Seed Synonym rows for the entity alias (one row per synonym group), for example via a data migration.

Synonyms are also injected into the index settings at creation time, so they persist across oro:search:reindex. Run oro:elasticsearch:search-synonyms:refresh to re-apply synonyms to existing indexes manually.

Extensibility 

The synonym filter is populated through the Oro\Bundle\ElasticSearchBundle\Event\ElasticSearchIndexSettingsEvent event (oro_elastic_search.index_settings), dispatched in Engine\IndexAgent before an index is created. Any bundle can listen to this event to inject custom analysis settings without patching the engine.

Listener example:

namespace Acme\Bundle\AcmeBundle\EventListener;

use Oro\Bundle\ElasticSearchBundle\Event\ElasticSearchIndexSettingsEvent;

class MyEntityIndexSettingsEventListener
{
    public function onIndexSettings(ElasticSearchIndexSettingsEvent $event): void
    {
        if ($event->getClass() !== \Acme\Bundle\AcmeBundle\Entity\MyEntity::class) {
            return;
        }

        $settings = $event->getSettings();
        $settings['analysis']['filter']['synonym']['synonyms'] = ['street, st', 'avenue, ave'];
        $event->setSettings($settings);
    }
}

Register the listener for the oro_elastic_search.index_settings event:

services:
    acme_bundle.event_listener.my_entity_index_settings:
        class: Acme\Bundle\AcmeBundle\EventListener\MyEntityIndexSettingsEventListener
        tags:
            - { name: kernel.event_listener, event: oro_elastic_search.index_settings, method: onIndexSettings }
