Updating Documents

Now let's try and update the same document with a change in the email address. The update command has a form of POST {index-name}/{type}/{id} and the request body as shown here:

POST datalake/contacts/101
{
  "id":101,
  "cell":"[phone]",
  "work":"1-906-774-1226",
  "email":"[email protected]"
}

Figure 30: Document Update Query

Few observations here in the preceding response are:

• The version is updated to 2.
• The flag created is set to false and the result indicates a successful update.
• Total shards affected are 3  since our index was configured to have 2 replicas and 4 shards. That means there are 3 shards having the affected data; one is the primary and the other two are replica shards.
