Subject [Solr Wiki] Update of "NearRealtimeSearch" by NagendraNagarajayya
Date Fri, 01 Jul 2011 16:29:32 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "NearRealtimeSearch" page has been changed by NagendraNagarajayya:
http://wiki.apache.org/solr/NearRealtimeSearch?action=diff&rev1=5&rev2=6

  
   * Special tuning for this scenario can be found on the NearRealtimeSearchTuning wiki page
  
- = Solr and NRT with RankingAlgorithm =
+ = Solr 1.4.1 and NRT with RankingAlgorithm =
   * NRT for Solr 1.4.1 is available with RankingAlgorithm. No changes are needed to your
code, except for enabling NRT in solrconfig.xml
   * The NRT functionality allows you  to add documents without the IndexSearchers being closed
or caches being  cleared. A commit is not needed with the document update. Searches can  run
concurrently with document updates. No changes are needed except for  enabling the NRT through
solrconfig.xml. The performance is about  262  TPS (document adds) on a dual core intel system
with 2GB heap with  searches in parallel. The performance at the moment is limited by how
 fast IndexWriter.getReader() performs.
   * More info about NRT (download tweets, schema, solrconfig.xml), http://solr-ra.tgels.com/papers/solr-ra_real_time_search.pdf
   * Download Solr with RankingAlgorithm from here, [[http://solr-ra.tgels.com/|http://solr-ra.tgels.com]]
  
+ = Solr 3.2 and NRT with RankingAlgorithm =
+  * NRT for Solr 3.2 is available with RankingAlgorithm. The performance is about 5000 TPS
(documents / sec). A new visible modifier can be used to tune when a document should be available
for search. More info available at http://solr-ra.tgels.com/wiki/en/Near_Real_Time_Search_ver3.2.
+  * Download Solr 3.2 with RankingAlgorithm from here, http://solr-ra.tgels.com
