Elasticsearch Populate In this chapter, let us learn how to add some index, mapping, and data to Elasticsearch. Note that some of this data will be used in the examples explained in this subject.

Create Index of Elasticsearch Populate

You can use the following command to create an index −

PUT school

Response

If the index is created, you can see the following output −

{"acknowledged": true}

Add data

Elasticsearch will store the documents we add to the index as shown in the following code. The documents are given some IDs which are used in identifying the document.

Request Body

POST school/_doc/10
{
   "name":"Saint Paul School", "description":"ICSE Afiliation",
   "street":"Dawarka", "city":"Delhi", "state":"Delhi", "zip":"110075",
   "location":[28.5733056, 77.0122136], "fees":5000,
   "tags":["Good Faculty", "Great Sports"], "rating":"4.5"
}

Response

{
   "_index" : "school",
   "_type" : "_doc",
   "_id" : "10",
   "_version" : 1,
   "result" : "created",
   "_shards" : {
      "total" : 2,
      "successful" : 1,
      "failed" : 0
   },
   "_seq_no" : 2,
   "_primary_term" : 1
}

Here, we are adding another similar document.

POST school/_doc/16
{
   "name":"Crescent School", "description":"State Board Affiliation",
   "street":"Tonk Road",
   "city":"Jaipur", "state":"RJ", "zip":"176114","location":[26.8535922,75.7923988],
   "fees":2500, "tags":["Well equipped labs"], "rating":"4.5"
}

Response

{
   "_index" : "school",
   "_type" : "_doc",
   "_id" : "16",
   "_version" : 1,
   "result" : "created",
   "_shards" : {
      "total" : 2,
      "successful" : 1,
      "failed" : 0
   },
   "_seq_no" : 9,
   "_primary_term" : 7
}

In this way, we will keep adding any example data that we need for our work in the upcoming chapters.

Adding Sample Data in Kibana
