+To use the same approach in CSOM, see the following example:
+```C#
+...
+if (startRow == 0) // When issueing the query for first time, we don't have a DocId value yet
+    keywordQuery.QueryText = "sharepoint";
+else  // Putting the IndexDocId first and then the 'actual' query matters (in this case searching for the keyword 'sharepoint')
+    keywordQuery.QueryText = string.Format("IndexDocId > {0} AND (sharepoint)", startRow);
+keywordQuery.EnableSorting = true;
+keywordQuery.SortList.Add("[DocId]", Microsoft.SharePoint.Client.Search.Query.SortDirection.Ascending);
+...
+```
+
+> [!NOTE]
+> When using the SortList in search queries, the fieldname being used must be enclosed by brackets (e.g. `[DocId]`).
