> :path cannot be used for searches, just for sorting: docValues is more than
> enough. In some cases, this could decrease the space taken for this specific
> field up to 50%.
> From the docs:
> https://www.elastic.co/docs/reference/elasticsearch/mapping-reference/doc-values
> "Doc-value-only fields: Numeric types, date types, the boolean type,... and
> the keyword type can also be queried when they are not indexed but only have
> doc values enabled. Query performance on doc values is much slower than on
> index structures, but offers an interesting tradeoff between disk usage and
> query performance for fields that are only rarely queried..."
