Question

我正在尝试使用带有Elasticsearch的Python从索引中读取文档。我收到找不到解决方案的错误。有谁知道我该如何解决？

我一直在网上寻找同样的问题，但是找不到任何相关的文章/解决方案。

这是我的代码：

from elasticsearch import Elasticsearch
from pandasticsearch import Select

# Connection to ElasticSearch
es = Elasticsearch(['http://localhost:9200'],timeout=600)

# Retrieving all documents in index (no query given)
documents = es.search(index='myindex',body={"query": {"match_all": {}}})

# Convert the result to Pandas Dataframe
pandas_df = Select.from_dict(documents).to_pandas()

*来源：https://medium.com/@patni.sonal/elasticsearch-convert-your-index-data-into-pandas-dataframe-30c44ada2407

我得到的错误是：

GET http://localhost:9200/myindex/_search [status:503 request:0.062s]
GET http://localhost:9200/myindex/_search [status:503 request:0.027s]
GET http://localhost:9200/myindex/_search [status:503 request:0.030s]

这是elasticsearch日志：

有人知道如何解决此问题吗？

Answer 1

我在启动 elasticsearch 服务后立即发送请求时遇到此错误。几秒钟后，我重试并成功执行了请求。

TransportError：TransportError（503，'search_phase_execution_exception'）
