[Solr Wiki] Update of "NearRealtimeSearch" by NagendraNagarajayya
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.
