1. 索引操作

1.1. 新建索引

from elasticsearch import Elasticsearch


es = Elasticsearch('http://localhost:9200', request_timeout=30, max_retries=5, retry_on_timeout=True)
index_name = "test"

create_result = es.indices.create(index=index_name)
print(create_result)

1.2. 删除索引

from elasticsearch import Elasticsearch


es = Elasticsearch('http://localhost:9200', request_timeout=30, max_retries=5, retry_on_timeout=True)
index_name = "test"

delete_result = es.indices.delete(index=index_name)
print(delete_result)

2. 插入数据

2.1. 单个数据插入

from elasticsearch import Elasticsearch


es = Elasticsearch('http://localhost:9200', request_timeout=30, max_retries=5, retry_on_timeout=True)
index_name = "test"

data = {"title": "各种信息"}
insert_result = es.index(index=index_name, body=data)
print(insert_result)

2.2. 批量数据插入

from elasticsearch import Elasticsearch
from elasticsearch import helpers


es = Elasticsearch('http://localhost:9200', request_timeout=30, max_retries=5, retry_on_timeout=True)
index_name = "test"

data = [
    {"title": "各种信息1"},
    {"title": "各种信息2"},
    {"title": "各种信息3"},
    {"title": "各种信息4"},
    {"title": "各种信息5"},
    {"title": "各种信息6"},
]
batch_size = 5
for index in range(0, len(data), batch_size):
    batch = [{"_index": index_name, "_type": "_doc", "_source": doc} for doc in data[index:index + batch_size]]
    insert_result = helpers.bulk(es, batch)
    print(insert_result)
