Ok, makes sense. However, when the core is initially created, the data is not yet there. Running the firstSearcher queries against empty index won’t have any beneficial effects when it comes to cache warming. Is there any way to open the first searcher after the data is pulled from the leader, and therefore, run the warmup queries? What’s the point of opening the first searcher when initially the core is created, if there is no data?
