I'm new to Elasticsearch, and I cannot find a Delete query.

Here is an example of an document in myIndex :

{
  "_index": "myIndex",
  "_type": "_doc",
  "_id": "IPc5kn8Bq7SuVr5qM9dq",
  "_score": 1,
  "_source": {
    "code": "1234567",
    "matches": [
      {
        "hostname": "hostnameA.com",
        "url": "https://www.hostnameA.com/....",
      },
      {
        "hostname": "hostnameB.com",
        "url": "https://www.hostnameB.com/....",
      },
      {
        "hostname": "hostnameC.com",
        "url": "https://www.hostnameC.com/....",
      },
      {
        "hostname": "hostnameD.com",
        "url": "https://www.hostnameD.com/....",
      },
    ]
  }
}

Let's say this index contains 10k documents.

I would like a query to remove all the item from my array matches where the hostname is equal to hostnameC.com, and keeping all the others.

Anyone would have an idea to help me?

  • As mentioned above, you will succeed if you reproduce the suggestion. Don't forget to match like this: ctx._source['matches'][i].hostname == 'hostnameC.com' Commented Jun 23, 2022 at 15:40
