An initialized operation object ready to continue the search.
Use this method to initialize a query operation that retrieves the next batch of results from a previous search. When executing searches based on a cursor, do not cache cursor objects for a long time before using them. A cursor is not a snapshot of the previous search results; it stores a relative offset into the results list. An operation object created using a cursor performs a new search, sorts the new set of results, and uses the previous offset value to determine where the next batch of results starts.
