If tags are assigned within a filter, allow results screens to be filtered by the tags.
- For v1, perhaps show all tags as filters, unless it's easy to limit the tag filters to only the ones used in the particular results set.
- Need to clarify what order they would appear (most heavily used in results set); just an input field with autocomplete fxn; input field is similar complexity to facets
- If a tag is removed from all records, suppress it from filter list of tags
- Comment from Jakub: figure out whether a facet or an input box is more appropriate
