Question

我已经将一些csv文件索引到Elasticsearch中，现在我正在尝试对某些列（基本上是两列）进行搜索。我想做： -精确搜索 -语音搜索 -模糊搜索 -同时进行语音和模糊搜索 -如果可能的话，一次将所有这些

请在下面找到我的ElasticSearch 6.5.1和Python 3.7的代码

import time
from elasticsearch import Elasticsearch
from elasticsearch import helpers

ELASTICSEARCH_HOST = "localhost"
ELASTICSEARCH_PORT = 9200
ELASTICSEARCH_INDEX_NAME = "phonetic_index"

es = Elasticsearch([{'host': ELASTICSEARCH_HOST, 'port': 
ELASTICSEARCH_PORT}])


def printSearchResult(caption, res):
    print(caption)
    hits = res['hits']['hits']
    for hit in hits:
        print("%0.2f %s" % (hit['_score'], hit['_source'] 
 ['text']))
    print("\n")


request_body = {
  "query": {
    "bool": {
      "must": [
        {
          "query": {
            "match": {
               "text.phonetic": {
                "query": "Meier"
              }
            }
          }
        }],
     "should" : [
        {
          "fuzzy": {
            "text": {
              "value": "Meier",
              "fuzziness": 2
            }
          }
        }
      ]
    }
  },
  "size" : 15
}


result_phonetic_and_fuzzy2 = es.search(index = 
ELASTICSEARCH_INDEX_NAME, body = request_body2)

printSearchResult("Result of search using phonetic search combined 
with fuzzy search with fuzziness 2:", result_phonetic_and_fuzzy2)

尝试代码时，出现以下错误

RequestError: RequestError(400, 'parsing_exception', 'no [query]

有人可以帮助我吗？

谢谢

无法在此处进行测试，但是非常确定您必须删除第二个查询。请告诉我是否可行。

request_body = {
  "query": {
    "bool": {
      "must": [
        {
            "match": {
               "text.phonetic": {
                "query": "Meier"
              }
            }
        }],
     "should" : [
        {
          "fuzzy": {
            "text": {
              "value": "Meier",
              "fuzziness": 2
            }
          }
        }
      ]
    }
  },
  "size" : 15
}
