In recent weeks our SOLR Search has begun to fail to return results from the Hybris application (times out after 180 seconds.) Rebuilding the Master SOLR index and replicating it to the Slave SOLR index has typically resolved the issue for us. But the last three days this has not worked and we are unable to get new products reflected in the SOLR search results from Hybris. However, we can still query the SOLR index from the SOLR admin console and see all old and new product changes. It's just that the Hybris application for some reason will not find any results on the the Slave SOLR index. In a review of all server and Dynatrace logs, we can see correct SOLR server name and its index file name is being used by the Hybris application. Any ideas on why we can directly query the SOLR index data outside the application, but get no results when going through the Hybris application?
