elasticsearchHow do I retrieve a document by its ID using Elasticsearch?

Retrieving a document by its ID using Elasticsearch is fairly straightforward. You can use the get API to fetch a document by its ID.

For example, if you have an index called my_index and a type called my_type, and the document has an ID of 1, you can use the following code to retrieve the document:

GET my_index/my_type/1

The output of this code should be a JSON object containing the document data.

The code can be broken down into the following parts:

  • GET: This is the HTTP verb used to retrieve a document.
  • my_index: This is the name of the index.
  • my_type: This is the type of the document.
  • 1: This is the ID of the document.

For more information, see the Elasticsearch documentation.
