Delete documents of type in Elasticsearch

Question

I want to delete all the documents indexed within a type in Elasticsearch, using the HTTP/REST api, but I don't want to delete the mapping for this type

How can I build the query in the URL to do this?

Answer 1

Before executing command, index/mapping state; (screenshots taken from elasticsearch head plugin web interface)

Command;

curl -XDELETE 'http://localhost:9200/publishercategoryeu/autocomplete/_query' -d '
{
  "query": {
    "bool": {
      "must": [
        {
          "match_all": {}
        }
      ]
    }
  }
}
'

Result;

After executing command, index/mapping state;

As we can see we deleted all the documents indexed within a type(mapping) without delete index or type(mapping).
