I'm wondered too, but it seems it warmups queryResultCache https://github.com/apache/lucene-solr/blob/20f9303f5e2378e2238a5381291414881ddb8172/solr/core/src/java/org/apache/solr/search/SolrIndexSearcher.java#L522 at least this ERRORs broke nothing see https://github.com/apache/lucene-solr/blob/20f9303f5e2378e2238a5381291414881ddb8172/solr/core/src/java/org/apache/solr/search/FastLRUCache.java#L165
anyway, here are two usability issues: - of key:org.apache.solr.search.QueryResultKey@62340b01 lack of readable toString() - I don't think regeneration exceptions are ERRORs, they seem WARNs for me or even lower. also for courtesy, particularly EarlyTerminatingCollectorExcepions can be recognized, and even ignored, providing SolrIndexSearcher.java#L522 Would you mind to raise a ticket?
