问题：

    meta, raw_data = node.perform_request(
  File "/home/server/miniconda3/envs/rag/lib/python3.8/site-packages/elastic_transport/_node/_http_urllib3.py", line 202, in perform_request
    raise err from None
elastic_transport.TlsError: TLS error caused by: TlsError(TLS error caused by: SSLError([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1131)))

当前，ElasticVectorSearch和 ElasticKNNSearch 为旧版 ，这里直接使用新版ElasticsearchStore

修改前：

    es_connection = ElasticsearchStore(embedding=embedings_h,index_name="hello-index",es_url = "https://192.168.0.133:9200",es_user = "elastic",es_password = "cwr9De0nHWPT27QyJMf+",distance_strategy = 'COSINE',)

添加 es_params = {"ca_certs":False,"verify_certs" : False} 字段即可

    es_connection = ElasticsearchStore(embedding=embedings_h,index_name="hello-index",es_url = "https://192.168.0.133:9200",es_user = "elastic",es_password = "cwr9De0nHWPT27QyJMf+",distance_strategy = 'COSINE',es_params = {"ca_certs":False,"verify_certs" : False},)

当前为快速验证阶段，不想看警告信息，可添加到头部

import urllib3
urllib3.disable_warnings()
