    Class
    Description
    CollectionStats
    Modifiable version of CollectionStatistics useful for aggregation of per-shard stats.
    ExactSharedStatsCache
    This class implements exact caching of statistics.
    ExactStatsCache
    This class implements exact caching of statistics.
    ExactStatsCache.ExactStatsSource
     
    LocalStatsCache
    Default implementation that simply ignores global term statistics, and always uses local term statistics.
    LocalStatsSource
    Convenience class that wraps a local SolrIndexSearcher to provide local statistics.
    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.
    StatsCache
    This class represents a cache of global document frequency information for selected terms.
    StatsCache.StatsCacheMetrics
     
    StatsSource
    The purpose of this class is only to provide two pieces of information necessary to create Weight from a Query, that is TermStatistics for a term and CollectionStatistics for the whole collection.
    StatsUtil
    Various utilities for de/serialization of term stats and collection stats.
    TermStats
    Modifiable version of TermStatistics useful for aggregation of per-shard stats.
