No way to search/associate for components with empty group or npm.scope

API : service/rest/v1/tags/associate and service/rest/v1/search

As npm artifacts can be published with a scope or without a scope into Nexus. So when associating the tag with a artifact without have scope is actually associating all the artifact with the same name and version irrespective of the scope.

Ex: Artifact with scope, group : org.dfs, name: npmApp, version : 1.0.0
Artifact without scope, name: npmApp, version : 1.0.0

Both are different, but associate API associates both artifact with the same tag ?

There needs to be a way to pass group (and npm.scope) as an empty string or null to indicate to associate to artifact with only name and version.
