What if I don't specify paging field while making a get request then maximum how many records will be retrieved?

[Ankit Agarwal]

selector = {
    :fields => ['Id', 'CriteriaType', 'KeywordText'],
    :predicates => [
      {:field => 'CampaignId', :operator => 'EQUALS', :values => [campaign_id]}
    ],
    :paging => {
      :start_index => 0,
      :number_results => PAGE_SIZE
    }
  }

Hi Ankit, 

If the page_size is not specified, it is automatically set to the maximum allowed page_size which is 10,000. Please refer to this section of the guide for more information.

Let me know if you have any questions. 

Thanks,
