The popularity of Solr has waned in recent years with Elasticsearch taking much of the "market share". I believe an important factor in this is the lack of options for forwarding logs to Solr.
Most of the log forwarding options target Elasticsearch out of the box. Splunk has its own dedicated universal forwarder. That makes it very easy to choose Elasticsearch or Splunk. Those who try Solr beyond the tutorial stage immediately run into problems forwarding log data to Solr. Logstash is a popular forwarding option that claims to target Solr. When you try to use it however there is a bug in the ruby code for RSolr that requires importing an older version and hand editing. It does not work out of the box. Most of the other log forwarding options suggest sending their logs to Logstash and having that forward them on to Solr. So, once a new user has finished testing with the tutorial data and is all enthusiastic about Solr, the nightmare begins when they try to send their own log data for indexing. I suspect most give up at this point and go to Elasticsearch and Splunk. They make ingestion easy. The solution? The Solr community could make the effort to fix Logstash, or develop a similar log forwarder that does work out of the box with Solr. Difficulty with log forwarding is a dealbreaker for many people. So, who is up for it?
