Struct CacheStatistics 

pub struct CacheStatistics {
    pub hits: u64,
    pub misses: u64,
    pub evictions: u64,
    pub current_size: usize,
    pub max_size: usize,
}

Number of cache misses (document not in cache).

evictions: u64

Number of document evictions due to cache size limit.

current_size: usize

Current number of documents in cache.

max_size: usize
