我是ElasticSearch以及干草堆的新手，并遵循教程:利用现有的常见问题解答来初始化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",
)
也试过简单的版本，如:
from haystack.document_stores import ElasticsearchDocumentStore
doc_store = ElasticsearchDocumentStore(
scheme="https",
host='localhost',
username='', password='',
index='test'
)
但是都失败了

我使用windows 10, elasticsearch版本是8.6(最新)，我不使用docker。任何帮助都是感激的!(ps.我已经看到了帖子Haystack's ElasticsearchDocumentStore()不能连接运行的ElasticSearch容器，但仍然没有关于如何做的线索。)
到目前为止(2023年1月)，Haystack还不支持elasticsearch version 8。我建议您使用版本7。您可以关注以下GitHub问题，其中跟踪了对版本8的支持:https://github.com/deepset-ai/haystack/issues/2810
我没有找到原始问题的直接解决方案，但我试图使用docker，一切都很好，elasticsearch版本为7.9.2。希望能帮助到有同样问题的人。
