Can Magento 2 Elastic Search Filter Results by Custom Attributes

Yes, Magento 2 Elastic Search can filter results by custom attributes when those attributes are added to the product index. Store owners can choose any field, like size or material, and make it searchable or filterable. Once indexing is done, customers can use these custom fields to refine results and find products faster. This reduces unwanted items and improves accuracy. Many stores also use range filters and multi select options. With the right setup and clear indexing, Magento 2 Elastic Search gives stores flexible control and better search performance.
