I am very excited to announce the availability of Apache Solr 4.0 with RankingAlgorithm 1.4.4 and Realtime NRT. Realtime NRT is a high performance and more granular NRT implementation as to soft commit. The update performance is about 70,000 documents / sec* (almost 1.5-2x performance improvement over soft-commit). You can also scale up to 2 billion documents* in a single core, and query half a billion documents index in ms**. Realtime NRT is different from realtime-get. realtime-get does not have search capability and is a lookup by id. Realtime NRT allows full search, see here for more info. Realtime NRT has been contributed back to Solr, see JIRA: https://issues.apache.org/jira/browse/SOLR-3816 RankingAlgorithm 1.4.4 supports the entire Lucene Query Syntax, � and/or boolean/dismax/boost queries and is compatible with the new Lucene 4.0 api. You can get more information about Solr 4.0 with RankingAlgorithm 1.4.4 and Realtime NRT performance from here: http://solr-ra.tgels.org/wiki/en/Near_Real_Time_Search_ver_4.x You can download Solr 4.0 with RankingAlgorithm 1.4.4 from here: http://solr-ra.tgels.org Please download and give the new version a try. Note: 1. Apache Solr 4.0 with RankingAlgorithm 1.4.4 is an external project Regards, Nagendra Nagarajayya http://solr-ra.tgels.org http://rankingalgorithm.tgels.org * performance is a real use case of Apache Solr with RankingAlgorithm as seen at a user installation ** performance seen when using the age feature --------------040802030301000300070605--
