Class ScanContext

java.lang.Object
  org.elasticsearch.search.scan.ScanContext

public class ScanContext
extends Object

The scan context allows to optimize readers we already processed during scanning. We do that by keeping track of the count per reader, and if we are done with it, we no longer process it by using a filter that returns null docIdSet for this reader.
