Get multiple documents
Generally available
All methods and paths for this operation:
Get multiple JSON documents by ID from one or more indices. If you specify an index in the request URI, you only need to specify the document IDs in the request body. To ensure fast responses, this multi get (mget) API responds with partial results if one or more shards fail.
Filter source fields
By default, the _source field is returned for every document (if stored).
Use the _source and _source_include or source_exclude attributes to filter what fields are returned for a particular document.
You can include the _source, _source_includes, and _source_excludes query parameters in the request URI to specify the defaults to use when there are no per-document instructions.
Get stored fields
Use the stored_fields attribute to specify the set of stored fields you want to retrieve.
Any requested fields that are not stored are ignored.
You can include the stored_fields query parameter in the request URI to specify the defaults to use when there are no per-document instructions.
Required authorization
- Index privileges:
read
Path parameters
-
Name of the index to retrieve documents from when
idsare specified, or when a document in thedocsarray does not specify an index.
Query parameters
-
Specifies the node or shard the operation should be performed on. Random by default.
-
If
true, the request is real-time as opposed to near-real-time. -
If
true, the request refreshes relevant shards before retrieving documents. -
Custom value used to route operations to a specific shard.
-
True or false to return the
_sourcefield or not, or a list of fields to return. -
A comma-separated list of source fields to exclude from the response. You can also use this parameter to exclude fields from the subset specified in
_source_includesquery parameter. -
A comma-separated list of source fields to include in the response. If this parameter is specified, only these source fields are returned. You can exclude fields from this subset using the
_source_excludesquery parameter. If the_sourceparameter isfalse, this parameter is ignored. -
If
true, retrieves the document fields stored in the index rather than the document_source.
