Updating a document using following query. Document gets updated successfully but I would like to know what are the various fields in response represents ?
Query:
POST test-square/test-square/bz773WoBVFIuuuSKDD_Q/_update
{
"doc": {
"user" : "kimchy-df",
"post_date" : "2009-11-15T14:12:12",
"message" : "trying out Elasticsearch"
}
}
Response:
{
"_index": "test-square",
"_type": "test-square",
"_id": "bz773WoBVFIuuuSKDD_Q",
"_version": 2,
"result": "updated",
"_shards": {
"total": 2,
"successful": 2,
"failed": 0
},
"_seq_no": 1,
"_primary_term": 1
}
successful = 2 ????
Why is successful = 2 when a single document is updated ?
