Kaltura API Python Script for adding tags to all entries in the account

addTagsToAllKalturaEntries.py

# This script loops through all media entries in a given Kaltura account
# and sets tags to all entries (it also checks if a list of tags is not already set on the entry before adding)
# this script requires the Kaltura Python 2.7 client library: http://www.kaltura.com/api_v3/testme/client-libs.php

I think it will get hit the 10k marks by using pagination. You cannot go beyond by using pager, right?

So, the way to get the next page of results is to build a list of object IDs that were already seen, then do the same search with those IDs excluded?

Doesn't Kaltura offer something like a results.getNextPage() method‽

If not, wouldn't it be better to just update the pageIndex property of an instance of KalturaFilterPager to get the next page?
