Which Elasticsearch version(s) do you support?

[jlarkin-auro]

Hello, I am having a problem executing a simple query.

I am running Elasticsearch 6.2.2 locally. From a clean installed base, I do

POST /accounts/person/ 
{
    "name" : "John",
    "lastname" : "Doe",
    "job_description" : "Systems administrator and Linux specialist"
}

I can then run:

GET /accounts/_search?q=name:john

which returns a proper result. I cannot reproduce this result with luqum however. I am trying:

from elasticsearch import Elasticsearch
client = Elasticsearch(host='localhost', port=9200)
client.info()

{'name': 'jQqh6TD',
 'cluster_name': 'elasticsearch',
 'cluster_uuid': 'vMnMGP4XRYC6CAJN7lOzyw',
 'version': {'number': '6.2.2',
  'build_hash': '10b1edd',
  'build_date': '2018-02-16T19:01:30.685723Z',
  'build_snapshot': False,
  'lucene_version': '7.2.1',
  'minimum_wire_compatibility_version': '5.6.0',
  'minimum_index_compatibility_version': '5.0.0'},
 'tagline': 'You Know, for Search'}

schema = client.indices.get_mapping(index='accounts')
schema

{'accounts': {'mappings': {'person': {'properties': {'address': {'properties': {'city': {'type': 'text',
        'fields': {'keyword': {'type': 'keyword', 'ignore_above': 256}}},
       'street': {'type': 'text',
        'fields': {'keyword': {'type': 'keyword', 'ignore_above': 256}}}}},
     'height': {'type': 'long'},
     'job_description': {'type': 'text',
      'fields': {'keyword': {'type': 'keyword', 'ignore_above': 256}}},
     'lastname': {'type': 'text',
      'fields': {'keyword': {'type': 'keyword', 'ignore_above': 256}}},
     'name': {'type': 'text',
      'fields': {'keyword': {'type': 'keyword', 'ignore_above': 256}}}}}}}}

from luqum.parser import parser
tree = parser.parse('name:john')
query = es_builder(tree)
query

{'match': {'name': {'query': 'john', 'zero_terms_query': 'none'}}}

response = client.search(
    index='accounts',
    body=query
)

This search returns the following stack trace:

Please advise on this. Perhaps I am missing something simple! Thank you very much.

Hello @jlarkin-auro, can you try

response = client.search(
    index='accounts',
    body={"query": query},
)

[alexgarel]

BTW, we do not know precisely which ES version we support right now ! We would have to do integration test for that (see #22)

hi @jlarkin-auro I would happy to know if my advice helped you (in this case I will rename ticket and close it).
