python

from elasticsearch import Elasticsearch
from elasticsearch import helpers

es_src=Elasticsearch(host_src)   #原索引所在ES集羣的host
es_des=Elasticsearch(host_des)   #新索引所在ES集羣的host

body={"query":{"match_all":{}}}  #遍歷原索引

helpers.reindex(client=es_src,source_index='wechat',target_index='wechat_new',target_client=es_des,query=body,chunk_size=1000) #重建索引
