{"mappings": {"properties": {"test":{"type": "nested"}}
}}GET test/_mappingPUT test/_doc/1
{"test":{"name":"ellis","age":100}
}

elasticsearch包

from elasticsearch import Elasticsearch
conn = Elasticsearch(hosts=['192.168.214.133'],port=31200,http_auth="elastic:ellischen")update_by_query = {"query": {"nested": {"path": "test","query": {"term": {"test.name": {"value": "ellis"}}}}},"script": {"source": "ctx._source['test']['age']+=1","params": {"age":101}, "lang": "painless"}
}conn.update_by_query(index='test',body=update_by_query)

elasticsearch-dsl包

from elasticsearch_dsl import connections
from elasticsearch_dsl import Search
from elasticsearch_dsl import Q as esQ
from elasticsearch_dsl import UpdateByQuery
conn = connections.create_connection(hosts=['192.168.214.133'],port=31200,http_auth="elastic:ellischen")
source = "ctx._source['test']['age']=params.age"
params = {"age":110}
query_body=esQ('nested',**{"path":'test',"query":esQ('term',**{"test.name":{"value":"ellis"}})})
update_by_query = UpdateByQuery().using(conn).index('test').query(query_body).script(source=source,params=params)update_by_query.execute()

from_dict 方法

from elasticsearch_dsl import connections
from elasticsearch_dsl import Search
from elasticsearch_dsl import Q as esQ
from elasticsearch_dsl import UpdateByQuery
conn = connections.create_connection(hosts=['192.168.214.133'],port=31200,http_auth="elastic:ellischen")
# source = "ctx._source['test']['age']=params.age"
# params = {"age":110}
# query_body=esQ('nested',**{"path":'test',"query":esQ('term',**{"test.name":{"value":"ellis"}})})
# update_by_query = UpdateByQuery().using(conn).index('test').query(query_body).script(source=source,params=params)# update_by_query.execute()update_by_query = {"query": {"nested": {"path": "test","query": {"term": {"test.name": {"value": "ellis"}}}}},"script": {"source": "ctx._source['test']['age']+=1","params": {"age":101}, "lang": "painless"}
}
search = UpdateByQuery().from_dict(update_by_query).using(conn).index('test')
search.execute()
