Updating your data

In this section, we will discuss different ways of updating existing documents. Internally, an update is always a delete and re-index. You can update using the entire document (replacing the original document), or update a single field or add a new field, or update a field using scripts, such as incrementing a counter.

Update using an entire document

When you index a document with the existing document ID, it will replace the current document with the new document. As shown next, we can update the document ID 1 using the entire document:

 PUT chapter4/person/1
 {
   "id": 1,
   "name": "name update 1",
   "age": 55,
   "gender": "M",
   "email"...
