I am trying to add additional fields to the Asset Finder for Content Fragments, so that content authors can search for fragments with specific tags and metadata fields, here:
AEM allows me to overlay search facets in the Asset Finder for Images by editing the Page Editor (Image search) form and adding predicates.
I cannot find where to overlay to do the same for Content Fragments. I need to add a tag filter as well as other custom metadata predicates. Looks like this is not possible to overlay, so what is the best way to do this customisation?
