Why not copy them into a facet field. Space constraints? If space is the concern, you need to remember that facets use indexed value, so that copy target field has absolutely no reason to be stored. And indexed values are stored only once per unique token, so then you are only paying for posting table, which is what you need anyway to do the counts.
