+    <!-- Solr Internal Query Caches
+
+         There are two implementations of cache available for Solr,
+         LRUCache, based on a synchronized LinkedHashMap, and
+         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)
+           size - the maximum number of entries in the cache
+           initialSize - the initial capacity (number of entries) of
+               the cache.  (see java.util.HashMap)
+           autowarmCount - the number of entries to prepopulate from
+               and old cache.
+           maxRamMB - the maximum amount of RAM (in MB) that this cache is allowed
+                      to occupy. Note that when this option is specified, the size
+                      and initialSize parameters are ignored.
+      -->

+         Additional supported parameter by LRUCache:
+            maxRamMB - the maximum amount of RAM (in MB) that this cache is allowed
+                       to occupy

+
+    <!-- Document Cache
+
+         Caches Lucene Document objects (the stored fields for each
+         document).  Since Lucene internal document ids are transient,
+         this cache will not be autowarmed.

+
+    <!-- Lazy Field Loading
+
+         If true, stored fields that are not requested will be loaded
+         lazily.  This can result in a significant speed improvement
+         if the usual case is to not load all stored fields,
+         especially if the skipped fields are large compressed text

+
+    <!-- Result Window Size
+
+         An optimization for use with the queryResultCache.  When a search
+         is requested, a superset of the requested number of document ids
+         are collected.  For example, if a search for a particular query
+         requests matching documents 10 through 19, and queryWindowSize is 50,
+         then documents 0 through 49 will be collected and cached.  Any further

+
+         If a search request comes in and there is no current
