Issue: ElasticsearchEmbeddings does not work on hosted elasticsearch (Platinum)

[lemig]

Issue you'd like to raise.

LangChain 0.0.179, hosted elasticsearch (Platinum edition)

V0.0.179 introduced elasticsearch embeddings, great!

But it is only implemented for elastic cloud.

I want to be able to do embeddings on my own elastic cluster.

I can add in the ability to use a url (the elasticsearch url) to the connection object rather than the cloud_id.

Would that work for you @lemig ?

[lemig]

I would rather pass ES client. If not, I need to pass an elasticsearch url plus elastic client options. See ssl_verify param in: https://github.com/hwchase17/langchain/commit/039f8f1abb03cc7983282bfa285920d00231e360#diff-6df1e93fbce8079475f40ff4465b79aa5e41131e63eb1d3c57b42b7779cb7adbR137

That should work. I'll take a look at it soon.

@lemig PR was merged.

# Create Elasticsearch connection
es_connection = Elasticsearch(
    hosts=['https://es_cluster_url:port'], 
    basic_auth=('user', 'password')
)

# Instantiate ElasticsearchEmbeddings using es_connection
embeddings = ElasticsearchEmbeddings.from_es_connection(
  model_id,
  es_connection,
)

Awesome. Thanks @jeffvestal & Elastic!
