How can I get an hit without a exact match with es 2.X? (Python elasticsearch)

Question

I have a problem with elasticsearch. There is an item ("'title': 'Using Python with Elasticsearch'") in the index. I can get the returned result only I searh the exact query. However, when I searh the "'title': 'Using Python with'", the code can hit nothing.
The es version is : {u'cluster_name': u'elasticsearch', u'tagline': u'You Know, for Search', u'version': {u'lucene_version': u'5.4.1', u'build_hash': u'd045fc29d1932bce18b2e65ab8b297fbf6cd41a1', u'number': u'2.2.1', u'build_timestamp': u'2016-03-09T09:38:54Z', u'build_snapshot': False}, u'name': u'Lorelei Travis'}
If I am right, it should be es 2.2.1. The code is attached. So, how can I get the hit, when I search with the query like "Using Python with", without an exact match query. Thanks!

INDEX_NAME = 'test_11'
from elasticsearch import Elasticsearch
es = Elasticsearch()
print es.info()

request_body = {  
      "mappings":{  
        "post":{  
          "properties":{  
            "title":{  
              "type":"string",
              "index":"analyzed"
            }
          }
        }
      }
    }

if es.indices.exists(INDEX_NAME):
    res = es.indices.delete(index = INDEX_NAME)
    print(" response: '%s'" % (res))

res = es.indices.create(index = INDEX_NAME, body=request_body)
print res

es.index(index=INDEX_NAME, doc_type='post', id=1, body={
  'title': 'Using Python with Elasticsearch'
  }
)

es.indices.refresh(index=INDEX_NAME)

res = es.search(index=INDEX_NAME, body={'query': {'match': {'title': 'Using Python with Elasticsearch'}}})
#res = es.search(index=INDEX_NAME, body ={"query":{"match":{"title":"Using Python with"}}})

print '\n'
res = es.indices.get(index=INDEX_NAME)
print res

Use a prefix query? If you want something fancier, consider regexp query or fuzzy query.

EDIT: Correct me if I am wrong: you want Using Python with to match all results like Using Python with Elasticsearch , Using Python with Lucene ? Then a mapping like:

request_body = {  
  "mappings":{  
    "post":{  
      "properties":{  
        "title":{  
          "type":"string",
          "index":"not_analyzed"
        }
      }
    }
  }
}

and then a query like:

{
    "query": {
        "prefix": {
            "title": "Using Python with"
        }
    }
}

Should return all the relevant documents. Note I changed the index field to not_analyzed .

EDIT 2: If you want to match all documents that contain the exact query anywhere in the target field, not just as a prefix, use a regexp query as suggested initially. Then

{
    "query": {
        "wildcard": {
            "name": "Using Python with*"
        }
    }
}

will work like a prefix query and match both Using Python with Elasticsearch as well as Using Python with Lucene , but

{
    "query": {
        "wildcard": {
            "name": "*Python with Elasticsearch"
        }
    }
}

will match Using Python with Elasticsearch only. It will not match Using Python with elasticsearch but you said you wanted exact phrase match.
