No Permission for Analytics Index Without Search Index Permissions
Keep in mind that in order for view / edit / add / delete permissions to an analytics index in a Relativity workspace to be effective, having those permissions alone is not enough. A user must also have permissions for the search index in order to use analytics index permissions.
Generally, only one search index is created for a workspace, but multiple indexes may be created if there are large sets of documents in multiple languages, or if searches need to be limited to a specific subset of documents.
A user with permissions to a search index without permissions to an analytics index, will still have those search index permissions activated.
