This class implements exact caching of statistics.

class |
LRUStatsCache
Unlike
ExactStatsCache this implementation preserves term stats
across queries in a set of LRU caches (with the same life-cycle as SolrIndexSearcher),
and based on surface features of a
query it determines the need to send additional requests to retrieve local term
and collection statistics from shards. |
