Hey,  
I am new to elasticsearch and was trying a piece of code to get all the documents from an index one by one but I got an error.  
The code was:  
\> from elasticsearch import Elasticsearch  
\> import pandas as pd  
\> es = Elasticsearch([{'host':'localhost', 'port':9200}])  
\> n=0  
\> while n \<=3:  
\> doc = {'size' : 1, 'query' : {'match all' : {}}}  
\> res = es.search(index = 'kibana\_sample\_data\_flights', doc\_type = "doc", body = doc, scroll = '1m')  
\> scroll = res['\_scroll\_id']  
\> res2 = es.scroll(scroll\_id = scroll, scroll = '1m')  
\> print("res", res)  
\> print('res2', res2)  
\> n += 1

The error I am getting is:  
Traceback (most recent call last):  
File "C:\Users\HP\Desktop\es\sample\_es1.py", line 19, in   
res = es.search(index = 'kibana\_sample\_data\_flights', doc\_type = "doc", body = doc, scroll = '1m')
