Hello Zhao-san Take a look at the cache and cost local parameters here: https://solr.apache.org/guide/solr/latest/query-guide/common-query-parameters.html#cache-local-parameter
If a filter query is not cached and it is very expensive, it is possible to tell Solr to execute it after all other q and fq using the above params. Otherwise I don’t exactly know in what order they are executed but my guess is they are all executed in parallel and later an intersection or union is made on their results. -ufuk — > On Dec 19, 2024, at 10:51, Mingchun Zhao <mingchun.zha...@gmail.com> wrote: > > Hi, > > When a search query includes both q and fq parameters, which one is > executed first internally (in Solr or Lucene)? > Additionally, is it possible to change this execution order? > > Regards, > Mingchun
