Hi @CodiDixon1,
The Elasticsearch Query and Elasticsearch Reader nodes provide an option Size that let you define the number of elements that should be returned for your query.
Although single ES queries only return max. 10,000 documents (based on the cluster configuration), the ES nodes internally use the Schopp API to circumvent this limitation. It should be fine to just set the size to 0 in order to receive all available documents. Let me know, if this does not solve your problem and we look deeper into it.
Best regards,
Daniel
