Searcher usage

------------------------------------------------------------------------------
   * '''Make sure you are using the latest version of Lucene.'''
  
   * '''Open a single writer and re-use it for the duration of your indexing session.'''
+ 
+  * '''Re-use your [http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/IndexSearcher.html searcher] at least until the index change.'''
+ 
+  Even better, wait until you need to match the new documents. Many caches are lost when opening a new searcher. Consider using a so called [http://wiki.apache.org/solr/SolrCaching warming] technique.
  
   * '''Flush by RAM usage instead of document count.'''
