You can configure Search caching through the /atg/search/routing/CacheService component. Key properties are:
defaultMaxElementsOnDisk- Set this property to a large number to avoid spending unnecessary resources purging the cache.defaultMemoryStoreEvictionPolicy- Least Recently Used (LRU) is the default. Other supported values are:FIFO(First In First Out) andLFU(Least Frequently Used).
When the configured memory amount for the cache is exceeded, the least recently used items are moved to disk; if the cache uses memory only, they are evicted.
