Taleo (TEE) Limit results in Candidate Search

Summary:

In Taleo > Recruiting, when searching for a Candidate under the "Look up a candidate", it returns all candidates regardless of whether they are internal, external, and/or not related to a requisition where the user is the owner or collaborator.

We wanted to limit the search results only to candidates that are related to requisitions where the user is the owner or collaborator. But there doesn't seem to be a config for this. I checked the User Type permission, but all I could do is hide the actual search candidate bar.

Has anyone tried limiting the search results when searching for candidates? Any tips? and I mean not based on the CSW, but more on the user should only see candidates based on the requisition they're affiliated with.
