Document level securityedit
Document level security restricts the documents that users have read access to. In particular, it restricts which documents can be accessed from document-based read APIs.
To enable document level security, you use a query to specify the documents that each role can access. The document query is associated with a particular index or index pattern and operates in conjunction with the privileges specified for the indices.
The following role definition grants read access only to documents that
belong to the click
category within all the events-*
indices:
POST /_security/role/click_role { "indices": [ { "names": [ "events-*" ], "privileges": [ "read" ], "query": "{\"match\": {\"category\": \"click\"}}" } ] }
Omitting the query
entry entirely disables document level security for
the respective indices permission entry.
The specified query
expects the same format as if it was defined in the
search request and supports the full Elasticsearch Query DSL.
For example, the following role grants read access only to the documents whose
department_id
equals 12
:
POST /_security/role/dept_role { "indices" : [ { "names" : [ "*" ], "privileges" : [ "read" ], "query" : { "term" : { "department_id" : 12 } } } ] }
query
also accepts queries written as string values.
