python - Elasticsearch : How to delete an Index using python

Question

如果这是非常基本的，请原谅我，但我有 Python 2.7 和 Elasticsearch 2.1.1，我只是想使用删除索引

es.delete(index='researchtest', doc_type='test')

但这给了我

return func(*args, params=params, **kwargs)
TypeError: delete() takes at least 4 arguments (4 given)

我也试过了

es.delete_by_query(index='researchtest', doc_type='test',body='{"query":{"match_all":{}}}')

但我明白了

AttributeError: 'Elasticsearch' object has no attribute 'delete_by_query'

知道为什么吗？ python 的 2.1.1 的 api 是否已更改？

对于 ES 8+ 使用:

from elasticsearch import Elasticsearch
es = Elasticsearch()

es.options(ignore_status=[400,404]).indices.delete(index='test-index')

对于旧版本，请使用此表示法:

from elasticsearch import Elasticsearch
es = Elasticsearch()

es.indices.delete(index='test-index', ignore=[400, 404])
