I'm trying to fetch data from Elasticsearch into an Eland dataframe partially, because it takes too much time to load the entire index.

The following works, except for the \_query\_compiler. The official [Eland docs](https://eland.readthedocs.io/en/latest/reference/api/eland.DataFrame.html) contains the parameter, but no description about how it works. I'm not even sure if this is the right approach though.

```plaintext
password = '..'
ip = '..'

es = Elasticsearch(hosts='https://{}:{}@{}'.format(username, password, ip), request_timeout=300, ca_certs='./Security/cert.pem')

index_name = '..'
index = ed.DataFrame(es_client=es, es_index_pattern=index_name, _query_compiler=???).to_pandas()

```

The following query seems to work, except for the part that it's not an Eland dataframe. (Also, the body parameter is deprecated but w/e.) There is a [related question](https://stackoverflow.com/questions/70685986/how-to-search-exact-index-not-index-pattern-in-elasticsearch-eland-updated) here, but it's not helping towards a solution.

```auto
search_body = {
            "query": {
                "match": {
                    "some_field": "true"
                }
              }
        }

results = es.search(index=index_name, body=search_body)

```
