Elasticsearch-py: Elasticsearch.search() unrecognized parameter: [analyzer]

[dengyuning]

The Elasticsearch-py API Document says that search(args, *kwargs) function has a parameter called 'analyzer'.
But the following code raise a RequestError:TransportError(400, 'illegal_argument_exception', 'request [/test-index/content-field/_search] contains unrecognized parameter: [analyzer]').
from elasticsearch import Elasticsearch
from elasticsearch.client import IndicesClient
es=Elasticsearch()
res= es.search(index="test-index", doc_type='content-field',body={"query": {"match": {"text": "微观文明"}}},analyzer="ik_smart")

PS: I am using version 5.0.1 for Elasticsearch-py and version 5.0.0 for elasticsearch.

That parameter is only used (and accepted) when using the q parameter to search via a query string. In your case you need to specify the analyzer for the match query in the body:

res= es.search(index="test-index", doc_type='content-field',body={"query": {"match": {"text": {"query": "微观文明", "analyzer": "ik_smart"}}}})

Hope this helps

Thank you so much! It helps!But I have to say the API document is kind of misleading.I suggest you add some explanation there.It's easy for those people who are quite familiar with Elasticsearch to find the mistake but not for the new beginners.

Thanks again!
