python: How to input a string and use it as query match elasticsearch

Question

I'm trying to code a simple python script which should ask for a string to be inserted by shell and use it as "match string" in a match query. I post here the script so the problem can be better understandable.

client = Elasticsearch()

query_string = raw_input("Enter your query string: ")
print(query_string)

s = Search(using=client, index="enron_test"
    .query("match", message_body=query_string))

response = s.execute()

Actually, I should get all the json documents (each represents an email) which contain the string "query_string" in the message_body field.

The problem is that when I run the script, I get this error: AttributeError: 'str' object has no attribute 'query'. I'm a newbie in Elasticsearch, where am I wrong? Or maybe this thing I'm trying to do is not possible?

Right now you are calling the query method on the string "enrox_test".

I dont know what library you are using so I cant check the syntax. But I think you are missing something between "enron_text" and ".query(..."

I'm using this libraries from elasticsearch import Elasticsearch and from elasticsearch_dsl import Search

You are missing a closing parenthesis after "enron-text". You can check out one of the search example here for the syntax of the search request here : elasticsearch-dsl.readthedocs.io/en/latest
