What is a content selector in Sonatype Nexus OSS 3.0?

Question

I was playing around with Sonatype Nexus OSS 3.0, trying to figure out how to pull off repository targets, when I came across content selectors. I am unable to find any documentation whatsoever on them, which I find odd.

What is a content selector, are they similar to repository targets, and how are they used? I am using Sonatype Nexus OSS 3.0.0-03.

Answer 1

Seems they added the documentation about ContentSelector in the 3.1 release.
