Is there any way to assign metadata to terms in a field and then filter on
that metadata when using that field as a facet?

For example, I have a collection of news articles in my index.  Each article
has a field that contains tags based on the topics discussed in the
article.  An article might have the tags "Barack Obama" and "Chicago".  I
want to assign metadata describing what type of entity each tag is.  For
these tags the metadata would be "person" for "Barack Obama" and "place" for
"Chicago".  Then I want to issue a facet query that returns only "person"
facets.

I can think of two possible solutions for this, both with shortcomings.

1) I could create a field for each metadata category.  So the schema would
have the fields "tag_person" and "tag_place".  The problem with this method
is that I am limited to filtering by a single criterion for each of my
queries.

2) I could leave the Solr schema unmodified and post-process the query.
This solution is less elegant than one that could be completely contained
within Solr.  I also imagine that it would be less performant.

Any thoughts?

Thanks in advance,

Asif
