: I am wondering if there is a way to warmup new searcher on commit by : rerunning queries processed by the last searcher. May be it happens by : default but then I can't understand why we see high query times if those : searchers are being warmed.
it only happens by default if you have an 'autowarmCount' enabled for each cache... https://lucene.apache.org/solr/guide/8_7/query-settings-in-solrconfig.html#caches But note that this warms the caches *individually* --it doesn't re-simular a "full request" so some things (like stored fields) may still be "cold" on disk. This typically isn't a problem -- eccept for people relying on FieldCache -- which is a query tie "un-inversion" of fields for sorting/faceting -- and has no explicit solr configuration or warming. for that you have to use soemthing like joel described -- static 'newSearcher' QuerySenderListenr queries that will sort/facet on those fields.... https://lucene.apache.org/solr/guide/8_7/query-settings-in-solrconfig.html#query-related-listeners ...but a better solution is to make sure you use DocValues on these fields instead. -Hoss http://www.lucidworks.com/
