# 3.6.5.缓存频繁聚合(Caching heavy aggregations)

经常使用的聚合（例如，用于在网站的主页上显示）可以被缓存以用于更快的响应。这些缓存的结果与未缓存的聚合返回的结果相同 - 您永远不会得到过时的结果。 有关详细信息，请参阅[Shard r](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-request-cache.html)[equest cache](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-request-cache.html)[。](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-request-cache.html)
