The shard query cache was introduced in 1.4 (https://www.elastic.co/guide/en/elasticsearch/reference/1.4/index-modules-shard-query-cache.html) and its stats were expanded in 2.0. From GET /_nodes/stats :

"indices": {
[...]
  "query_cache": {
    "memory_size_in_bytes": 113135344,    <= 1.4
    "evictions": 1160944,                 <= 1.4
    "hit_count": 95698008,                <= 1.4
    "miss_count": 1238003499,             <= 1.4
    "total_count": 1333701507,            <= 2.0
    "cache_size": 10633,                  <= 2.0
    "cache_count": 1171577                <= 2.0
  }
[...]
}

This can easily build up on the work done in #2186 and #2232. PR to follow.
