NXUI: Compound Documents search

NXUI: Compound Documents search

This epic will define how search is handled on Compound docs

The basic concept is the following:

I need the metadata from all my children files to be accessible via my parent, such that I can search for parent files only but get complete results

I want to search for assets that are child components of compound assets; searching/filtering on normal fields (e.g. expiration date) and then filtering to only assets that are children of compound documents. Then select one and view all the parent docs the component is used in.
