   * '''Re-open the [http://lucene.apache.org/java/docs/api/org/apache/lucene/search/IndexSearcher.html IndexSearcher] only when necessary.'''
  
-  You must re-open the [http://lucene.apache.org/java/docs/api/org/apache/lucene/search/IndexSearcher.html IndexSearcher] in order to see make newly committed changes visible to searching.  However, re-opening the searcher has a certain overhead (noticeable mostly with large indexes and with sorting turned on) and should thus be minimized.  Consider using a so called [http://wiki.apache.org/solr/SolrCaching warming] technique which allows the searcher to warm up its caches before the first query hits.
