When making an aggregation query to ElasticSearch, in some cases it is necesary to get non-analyzed field value for getting proper non-tokenized strings (i.e.: Getting all sections used in some website by stories with use-count on each).
There are some fields (such as `taxonomy.tags.text`) which has `.raw` multi field mapped in order to provide access to this type of queries.
Can we have the same kind of mapping for `taxonomy.primary_section.name` or `taxonomy.sections.name`?
