我是ElasticSearch和Haystack的新手，按照Tutorial: Utilizing Existing FAQs for Question Answering使用代码初始化DocumentStore：

import os
import time

from haystack.document_stores import ElasticsearchDocumentStore

# Wait 30 seconds only to be sure Elasticsearch is ready before continuing
time.sleep(30)

# Get the host where Elasticsearch is running, default to localhost
host = os.environ.get("ELASTICSEARCH_HOST", "localhost")

document_store = ElasticsearchDocumentStore(
    host=host,
    username="",
    password="",
    index="document",
    embedding_field="question_emb",
    embedding_dim=384,
    excluded_meta_data=["question_emb"],
    similarity="cosine",
)

还尝试了简单版本，如：

from haystack.document_stores import ElasticsearchDocumentStore
doc_store = ElasticsearchDocumentStore(
    scheme="https",
    host='localhost',
    username='', password='',
    index='test' 
)

但都失败了错误：

我用的是windows10，elasticsearch版本是8.6（最新版），我不用docker。任何帮助都很感激！（附言：我看过Haystack's ElasticsearchDocumentStore() cannot connect running ElasticSearch container的帖子，但仍然不知道该怎么做。）
