+         FastLRUCache, based on a ConcurrentHashMap.
+
+         FastLRUCache has faster gets and slower puts in single
+         threaded operation and thus is generally faster than LRUCache
+         when the hit ratio of the cache is high (> 75%), and may be
+         faster under other scenarios on multi-cpu systems.
+    -->
+
+    <!-- Filter Cache
+
+         Cache used by SolrIndexSearcher for filters (DocSets),
+         unordered sets of *all* documents that match a query.  When a
+         new searcher is opened, its caches may be prepopulated or
+         "autowarmed" using data from caches in the old searcher.
+         autowarmCount is the number of items to prepopulate.  For
+         LRUCache, the autowarmed items will be the most recently
+         accessed items.
+
+         Parameters:
+           class - the SolrCache implementation LRUCache or
+               (LRUCache or FastLRUCache)

+           initialSize - the initial capacity (number of entries) of
+               the cache.  (see java.util.HashMap)
+           autowarmCount - the number of entries to prepopulate from

+                      to occupy. Note that when this option is specified, the size
