Now i want to know if its useful to update on a new solr version. My version is: 4.0.0.2010.10.26.08.43.14 I need a really good NRT search for my application, and i realized it with several cores/indices and each of them is splitted into one core for search request and another core for indexing. my dih need ~15 seconds for 1500 docs to index in my "main" and biggest index. its not so bad. but make it sense to use a newer version of solr, with hard- and soft-commits? in specially i want to split my 50M index into several smaller index for a faster search, update and optimizations. ----- ------------------------------- System ---------------------------------------- One Server, 12 GB RAM, 2 Solr Instances, 8 Cores, 1 Core with 45 Million Documents other Cores < 200.000 - Solr1 for Search-Requests - commit every Minute - 5GB Xmx - Solr2 for Update-Request - delta every Minute - 4GB Xmx -- View this message in context: http://lucene.472066.n3.nabble.com/new-NRT-in-my-case-quite-useful-tp3572433p3572433.html Sent from the Solr - User mailing list archive at Nabble.com.
