you can pass an aggregationParam "size" with the FacetConfigTransfer

I agree to @UN96SRMN0. We implemented it as follows:

class ProductSearchConfigExpanderPlugin extends SprykerProductSearchConfigExpanderPlugin
{
    private const FIELD_NAME = 'integer-facet';
    private const MAX_SIZE = 999;

    /**
     * @return \Generated\Shared\Transfer\SearchConfigExtensionTransfer
     */
    public function getSearchConfigExtension()
    {
        $productSearchConfigExtensionTransfer = new SearchConfigExtensionTransfer();
        $key = $this->getKey();
        $data = $this->getProductSearchConfigExtensionData($key);
        if ($data !== null) {
            $data = $this->changeFilterFacetMaxSize($data);
            $productSearchConfigExtensionTransfer->fromArray($data, true);
        }

        return $productSearchConfigExtensionTransfer;
    }

    /**
     * @param array $data
     *
     * @return array
     */
    private function changeFilterFacetMaxSize(array $data): array
    {
        if ($data['facet_configs'] !== null) {
            foreach ($data['facet_configs'] as $key => $facet) {
                if ($facet['field_name'] !== static::FIELD_NAME) {
                    $facet['aggregation_params']['size'] = static::MAX_SIZE;
                    $data['facet_configs'][$key] = $facet;
                }
            }
        }

        return $data;
    }
}

I hope it works on ES 7 also.
