Ah, that may make my suggestions unworkable re: just reindexing. Still, how much time are we talking about here? I've very often found that indexing performance isn't gated by the Solr processing, but by whatever is feeding Solr. A quick test is to fire up your indexing and see if the CPU utilization by Solr is very high. As Toke said, though, if you're using DIH you're out of luck.
Here's an article to get you started with SolrJ: http://lucidworks.com/blog/indexing-with-solrj/ Best, Erick On Thu, Sep 3, 2015 at 10:26 AM, Toke Eskildsen <t...@statsbiblioteket.dk> wrote: > scott chu <scott....@udngroup.com> wrote: >> No, both.
