I am working with PIMCO who has migrated from Qvidian. We implemented Hierarchal tags for them to mimic their folder structure. One piece of feedback would be how H-Tags work in filters. Right now to eliminate a child or grand-child tag from the parent hierarchy you have to use the advanced filters. For the facet filters, one enhancement would be when you select the parent tag, all the children/grandchildren also get selected and you can deselect what you don't want to see. Please let me know if you'd like to chat about this or want a call recording where we discussed it. @
