/**
 * Due to the limitation of the API, we can get a maximum of 5000 rows at a time. Another limitation is that, results are sorted by click count descending. If two rows have the same click count, they are sorted in an arbitrary way. (Read more at https://developers.google.com/webmaster-tools/v3/searchanalytics). So we try to get all pages by partitions, if a partition has 5000 rows returned. We try partition current partition into more granular levels.
