Shawn, thanks so much, and this user forum is so helpful! I will start use autocommit with confidence it will greatly help reducing the false commit requests (a lot) from processes in our system.
Regarding the solr version, it is actually a big problem we have to resolve sooner or later. When we upgraded to Solr 3.5 about 2 years ago, to avoid re-index our large data, we used : <luceneMatchVersion>LUCENE_29</luceneMatchVersion> which seems to work fine except a lot of such warnings in catalina.out: WARNING: StopFilterFactory is using deprecated LUCENE_29 emulation. You should at some point declare and reindex to at least 3.0, because 2.x emulation is deprecated and will be removed in 4.0 We have a built a infrastructure which scales well using solr, is it a good practice to upgrade to solr 4.x without using solrCloud if it is possible at all? thanks!
