filters of reference data attributes not working in product_model_index

[jotalops]

In version 2.4 of the bundle ( akeneo 2.3 )

if we do a simple search by an attribute of type reference data simple or multiple we dont't found any results.

+++++++++++++++++
$pqbFactory = $this->getContainer()->get('pim_catalog.query.product_model_query_builder_factory');

/* @var ProductAndProductModelQueryBuilder $pqb */
$pqb = $pqbFactory->create(['default_locale' => 'en_US', 'default_scope' => 'ecommerce']);
$pqb->addFilter('rd_brand', 'IN', [$brandCode]);

debugging the error I found that the index product_model_index is not used by the reference data normalizers

to resolve the issue we must add that index to the normalizers:

ReferenceDataCollectionNormalizer.php
ReferenceDataNormalizer.php

we must include in the supportsNormalization method that index

....
use Pim\Component\Catalog\Normalizer\Indexing\ProductModel\ProductModelNormalizer as ProductModelNormalizer2;

....
public function supportsNormalization($data, $format = null)
{
return $data instanceof ReferenceDataCollectionValue && (
ProductNormalizer::INDEXING_FORMAT_PRODUCT_INDEX === $format ||
ProductModelNormalizer::INDEXING_FORMAT_PRODUCT_AND_MODEL_INDEX === $format
|| ProductModelNormalizer2::INDEXING_FORMAT_PRODUCT_MODEL_INDEX
);
}
......
public function supportsNormalization($data, $format = null)
{
return $data instanceof ReferenceDataValue && (
ProductNormalizer::INDEXING_FORMAT_PRODUCT_INDEX === $format ||
ProductModelNormalizer::INDEXING_FORMAT_PRODUCT_AND_MODEL_INDEX === $format
|| ProductModelNormalizer2::INDEXING_FORMAT_PRODUCT_MODEL_INDEX
);
}

I attached the fix
