使用Elastic Search，如何将包含数组的文档索引到多个文档中，每个数组项一个文档？

from elasticsearch import Elasticsearch

# 创建Elasticsearch客户端
es = Elasticsearch()

# 创建索引
index_name = "my_index"
es.indices.create(index=index_name)

# 定义映射
mapping = {
    "properties": {
        "my_array": {
            "type": "nested"
        }
    }
}
es.indices.put_mapping(index=index_name, body=mapping)

# 索引文档
doc = {
    "my_array": [
        {"name": "item1"},
        {"name": "item2"},
        {"name": "item3"}
    ]
}

for item in doc["my_array"]:
    es.index(index=index_name, body=item)

# 查询文档
query = {
    "query": {
        "nested": {
            "path": "my_array",
            "query": {
                "match": {
                    "my_array.name": "item1"
                }
            }
        }
    }
}

result = es.search(index=index_name, body=query)
print(result)
