Those do different things. One caches the combined results and one caches each term. To be honest term filter are rarely worth caching because just hitting lucene for them is so fast. 2.

They are applied to new segments to eagerly load stuff including the filter cache. Elasticsearch's filer cache is per segment so this is a good match. Its also why the filter cache doesn't have to be invalidated - segments are write only and deletes are applied after the results from the filter cache.
