The `source` property of `elasticsearch_dsl.Search` is used to define the fields or properties of the indexed documents that should be included in the search results. By specifying the `source`, you can control which fields are returned for each document, reducing the amount of data transferred and improving the search performance. It allows you to selectively filter and retrieve only the required information from the Elasticsearch index, making the search process more efficient.
