为什么此ElasticSearch扫描和滚动返回IndexMissingException

Question

I run the following:

curl -XGET 'http://my_address/my_index/_search?scroll=1m&size=10&search_type=scan' -d '{'query':{'match_all':{}}}'

It returns a scroll id (very long), and I then use in the first scroll request:

curl -XGET 'http://my_address/my_index/_search/scroll?scroll=1m' -d '<scroll_id>'

It returns an error: {"error":"IndexMissingException[[my_index] missing]","status":404}

I do not know why having this error. I follow the guideline in https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html step by step.

What is going on?

Answer 1

因为您的第二个请求（即使用scroll_id ）不应获取任何索引，而是这样读取：

curl -XGET 'http://my_address/_search/scroll?scroll=1m' -d '<scroll_id>'
