text: user9344: Is there a limit of query results on RCSB API?
  Interestingly, no matter how to adjust my query criteria, only 10 assemblies are returned. Here is an example query json: (truncated from a longer query file)
  {
    "query": {
      "type": "group",
      "logical_operator": "and",
      "nodes": [
        {
          "type": "terminal",
          "service": "text",
          "parameters": {
            "operator": "greater",
            "value": 1,
            "attribute": "rcsb_assembly_info.polymer_entity_instance_count"
          }
        }
      ]
    },
    "return_type": "assembly"
  }
  
  Example python code requesting query:
  url_query = 'https://search.rcsb.org/rcsbsearch/v1/query?json='
  query_str = open(query_json, 'r').read()
  query_str = query_str.replace('\n', '').replace(' ', '')
  url = url_query + query_str
  
  r = requests.get(url)
  content = r.content.decode('utf-8')
  result = json.loads(content)
  print(len(result['result_set']) # always equal to 10
  
  
  user9344: Staff from rcsb kindly reminds me the solution - add the following lines in the json query.
  "request_options": {
  "return_all_hits": true
  }
