The Search Notice Request and Response support the ability to iterate over a large result set matching a query by allowing multiple QueryRequest requests to be submitted in succession such that each query requests a different subset of results within the result set. This feature enables the server to handle queries that match a very large result set, in a scalable manner. This attribute is used to indicate which result must be returned as the first result when iterating over a large result set. The default value is 0, which returns the result set starting with index 0 (first result).
