python-3.x - 使用 python 为 elasticsearch 6.x 调用_analyze

Question

如何调用

POST my_index/_analyze
{
  "analyzer": "german_analyzer",
  "text": "kann"
}

在 python Elasticsearch 6.x api 中？

我试过了

def get_es():

    # Variables for Elasticsearch host+port
    es_host = 'localhost'
    es_port = 9200

    from elasticsearch import Elasticsearch
    es = Elasticsearch([{'host': es_host, 'port': es_port}])
    return es

if __name__ == '__main__':

    es = get_es()
    body={
      "analyzer": "german_analyzer",
      "text": "kann"
    }
    result = es.search(index="faq-kbaid-de-index", body=body,
                               size=1)
    i=1

它给出异常

elasticsearch.exceptions.RequestError: RequestError(400, 'parsing_exception', 'Unknown key for a VALUE_STRING in [analyzer].')

Answer 1

es.search() 调用 _search。您可以通过 elasticsearch.client.IndicesClient 调用 _analyze .将 .search 行替换为

result = es.indices.analyze(index="faq-kbaid-de-index", body=body,
                           size=1)
