> Hey Denis, > * How big is your index in terms of number of documents and index size? 5 cores, average 250.000 documents, one with about 1 million (but without text, just int/float fields), one with about 10 million id/name documents, but with n-gram. Size: 4 databases about 1G (sum), 1 database (with n-gram) for 21G.. I don't know any other way to search for product names except n-gram =\
> * Is it production system where you have many search requests? Yes, dependent on database, but not less than 100 req/sec > * Is there any pattern for OOM errors? I.e. right after you start your > Solr app, after some search activity or specific Solr queries, etc? No, java just raises memory size used all the time until it crush. > * What are 1) cache settings 2) facets and sort-by fields 3) commit > frequency and warmup queries? All settings are default (as given in trunk / example). Facets are used, sort by also used. Commits are divided into 2 groups: - often but small (last changed info) - 1 time per day all the database > etc > Generally you might want to connect to your jvm using jconsole tool > and monitor your heap usage (and other JVM/Solr numbers) > * http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html > * http://wiki.apache.org/solr/SolrJmx#Remote_Connection_to_Solr_JMX > HTH, > Alexey
