What does the queryMore() function do?

The queryMore() function is designed to facilitate the retrieval of additional records from a query that has resulted in a response containing a limited number of records. In many situations, particularly with large datasets, initial queries might not return all possible records due to limits set by the platform or service being used. Instead, they return a specific number of results and provide a mechanism, through the use of a queryMore() call, to fetch the next set of results.

When a query is executed, a cursor or a 'next page' reference is typically returned, which can be used in subsequent calls to pull further records. This allows developers to manage large volumes of data systematically and efficiently, ensuring they can access all the relevant records across multiple requests rather than in a single transaction. Thus, retrieving more records than the initial query allows is the pivotal function of queryMore(), making the selection correct.
