python中elasticsearch是什么？

pip install elasticsearch

from elasticsearch import ElasticSearch

es = ElasticSearch(['localhost:9200'])

es.indices.create(index='project', ignore=400)

es.indices.delete(index='project', ignore_unavailable=True)

for i in range(10):

    body = {

        'name': '张三' % i,

        'age': 20 + i,

        'desc': '我是张家的老' % i

    }

    es.create(index='project', doc_type='_doc', body=body, id=i)
