Query result cache statistics
Record core-specific query result cache statistics over time.
The core result cache statistics is exposed through its registered index searcher, but the core may have many index searchers over its lifetime. To reflect the index searchers, statistics for the currently registered searcher are provided with cumulative/lifetime statistics.
