Assuming I get the total number of documents to be 10, each of the documents have their unique IDs. How do I choose random documents from there

Ok if I understand you clearly, if random_number is 7, document and position 7 will be gotten?

If the random_number is from the random library, why do we limit it to 1? Because I think its already 1
