https://issues.apache.org/jira/browse/SOLR-17058 # Description When distributed IDF is enabled in solr cloud by adding one of the cache implementations in solrconfig.xml https://solr.apache.org/guide/solr/latest/deployment-guide/solrcloud-distributed-requests.html#distributedidf, each solr query will incur a distributed shard request to get term statistics. For queries that does not use distributed IDF information for scoring, the stats request is not necessary. # Solution Hence I propose to add a disableDistribStats request param so that the distributed stats request can be disabled at query time. 1. disableDistribStats defaults to false. When the param is not present, there is no change to current distributed IDF behavior. 2. When explicitly set disableDistribStats=true, distributed stats call is disabled for the current query. # Tests Added unit tests related to distrib IDF and query result key. # Checklist Please review the following and check all that apply: - [ X] I have reviewed the guidelines for [How to Contribute](https://wiki.apache.org/solr/HowToContribute) and my code conforms to the standards described there to the best of my ability. - [X ] I have created a Jira issue and added the issue ID to my pull request title. - [ ] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
