Python query ElasticSearch path with backslash - python-2.7

Question

I'm using the Elastic search extension to Python, trying to query specific path.
Here is my wrapped query:
{
"size": 1000,
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"term": {
"Path": "c:\\myfolder\\myfile.txt"
}
}
]
}
}
}
}
}
Which works fine in kopf plugin.
Here is my Python code:
from elasticsearch import Elasticsearch
es = Elasticsearch(hosts=['my_server'])
index = "my_index"
query = '{"size":1000,"query":{"filtered":{"filter":{"bool":{"must":[{"term":{"Path":"c:\\myfolder\\myfile.txt"}}]}}}}}'
response = es.search(index=index, body=query)
For some reason I'm getting this error (which will not occur without the backslash):
/usr/local/lib/python2.7/dist-packages/elasticsearch/client/utils.py",
line 69, in _wrapped
return func(*args, params=params, **kwargs) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/client/init.py",
line 530, in search
doc_type, '_search'), params=params, body=body) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/transport.py",
line 329, in perform_request
status, headers, data = connection.perform_request(method, url, params, body, ignore=ignore, timeout=timeout) File
"/usr/local/lib/python2.7/dist-packages/elasticsearch/connection/http_urllib3.py",
line 106, in perform_request
self._raise_error(response.status, raw_data) File "/usr/local/lib/python2.7/dist-packages/elasticsearch/connection/base.py",
line 105, in _raise_error
raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.RequestError
This problem happens only when there are backslashes.
Note: I'm working on Ubuntu.
Thanks in advance.

Try changing the "Path" to c:\\\\myfolder\\\\myfile.txt.
