Elasticsearch-py在搜索中無法識別'analyzer'參數（）

Question

API文檔說search(*args, **kwargs)有一個名爲analyzer的參數。但是，下面的代碼會引發異常：

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": "微觀文明"}}}, 
       analyzer="ik_smart", size=3) 

下面的代碼，然而，返回一個正確的答案。

i=IndicesClient(es) 
res=i.analyze(index="test-index",body="我你大家",analyzer="ik_smart") 

Answer 1

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[.]
