如何使用python将修改后的索引中的内容复制到Elasticsearch中的另一个索引中

pip install elasticsearch

from elasticsearch import Elasticsearch

es = Elasticsearch(hosts=['localhost'])

source_index = 'source_index'
query = {
    "query": {
        "match_all": {}
    }
}

result = es.search(index=source_index, body=query)

target_index = 'target_index'

mapping = {
    "mappings": {
        "properties": {
            "field1": {"type": "text"},
            "field2": {"type": "keyword"}
        }
    }
}

es.indices.create(index=target_index, body=mapping)

for doc in result['hits']['hits']:
    source_doc_id = doc['_id']
    source_doc = doc['_source']
    
    es.index(index=target_index, body=source_doc, id=source_doc_id)
