elasticsearch_dsl 添加数据

要使用elasticsearch_dsl添加数据，首先需要建立与ElasticSearch的连接。可以使用以下代码创建连接：

from elasticsearch_dsl import connections
connections.create_connection(hosts=['127.0.0.1:9200'], timeout=20)

接下来，您需要获取要添加数据的index和table信息。您可以使用以下代码获取index和table的名称：

from elasticsearch import Elasticsearch
from elasticsearch_dsl import Search

client = Elasticsearch('127.0.0.1:9200')
indexs = client.indices.get('*')
indexnames = indexs.keys()

index = indexnames<span class="em">1</span><span class="em">2</span>
