Kevin - you can also use that same type of query to search sections.

For example:  tag_section:news and tag_section:business

Would only show assets that are in BOTH sections.
That's correct Christine.  The secure domain for madison which we host is:host-dot-madison-dot-com.bloxcms.com which tests clean.

We're definitely wanting to add this in to TCMS - it just gets very complicated.

We have customers that may have a TCMS site feeding multiple websites. The Broadcast channels may not line up one to one from TCMS to the website - it almost needs to be tied into the site tag somehow.
