Elastic Stack Elasticsearch
1

Hi team,

when insert data to elasticsearch, i have
GET /news/testing/
GET /news/trkd/
GET /news/nar/

the type will be different. How to delete the type i need?
when i use DELETE news/trkd/ , the error will be show 'No handler found for uri [/news/trkd/] and method [DELETE]'.
If i use DELETE news/ it will success, but it will delete all type i insert.
How to delete type i need ?

Thanks and Best regards
Sharon

Hi @Sharon_wsf,

you need to install the delete by query plugin and then delete all documents belonging to that type with a query, e.g.:

DELETE /news/testing/_query
{
  "query": { 
      "match_all": {}
  }
}

A better solution is to use multiple indexes instead of multiple types. You can use aliases to assign alternative names to indices.
