> Does this happen on a warm searcher (are subsequent requests with no intervening updates _ever_ fast?)?
Subsequent response times very fast if searcher remains open. As a control test, I faceted on the same field that I used in the q param. 1. Start solr 2. Execute q=resultId:xxxxx&rows=0 => 500ms 3. Execute q=resultId:xxxxx&rows=0&json.facet-on-resultId => 40,000ms 4. Execute q=resultId:xxxxx&rows=0&json.facet-on-resultId => 150ms 5. Execute q=processId:xxxxx&rows=0&json.facet-on-processId => 2,500ms 6. Execute q=processId:xxxxx&rows=0&json.facet-on-processId => 200ms curl 'http://localhost:8983/solr/TestCollection_shard1_replica_t3/query?q=processId:xxxx-xxx-xxx-xxx-xxxxx&rows=0' -d ' json.facet={ categories:{ "type": "terms", "field" : "processId", "limit" : 1 } } -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
