Retrieve stored fields using the Get document API
Elastic Stack
Use the stored_fields
query parameter in a Get document API request to retrieve fields marked as stored ("store": true
) in the index mapping.
Fields not marked as stored are excluded from the response, even if specified in the request.
For example, these PUT requests define a stored field in the mapping and add a document:
PUT my-index-000001
{
"mappings": {
"properties": {
"counter": {
"type": "integer",
"store": false
},
"tags": {
"type": "keyword",
"store": true
}
}
}
}
PUT my-index-000001/_doc/1
{
"counter": 1,
"tags": [ "production" ]
}
This request retrieves the stored fields from the document:
GET my-index-000001/_doc/1?stored_fields=tags,counter
The API returns the following response:
{
"_index": "my-index-000001",
"_id": "1",
"_version": 1,
"_seq_no": 22,
"_primary_term": 1,
"found": true,
"fields": {
"tags": [
"production"
]
}
}
Although the counter
field is specified in the request, it's not included in the response because it's not actually a stored field.
Field values are returned as an array.
Only leaf fields can be retrieved with the stored_fields
parameter. If you specify an object field instead, an error is returned.
