模糊这样(FLT) - ElasticSearch

Question

我正在努力将FLT应用到我正在构建的原型ES系统中.我已经查看了Elasticsearch网站上的文档,虽然它已经存在,但我似乎无法实现这一点.也许有人可以给我一些关于如何做到这一点的见解.

我似乎无法在网络上的其他地方找到任何这方面的例子,但也许我的谷歌技能今天没有达到标准.这是我到目前为止设法建造的 -

$ curl -XGET 'http://127.0.0.1:9200/uber/uber/_search?'  -d '{
  "fuzzy_like_this": {
    "fields": [
      "pty_firstname",
      "pty_surname"
    ],
    "like_text": "Nathan Andew",
    "max_query_terms": 12
  }
}'

以下是我在发送请求时从提示中收到的错误消息 -

  "error":"SearchPhaseExecutionException[Failed to execute phase [query], total failure;

}

我认为您缺少查询部分,您需要执行以下操作:

$ curl -XPOST 'http://127.0.0.1:9200/uber/uber/_search?'  -d '
{
  "query" : {
    "fuzzy_like_this" : {
       "fields" : ["pty_firstname", "pty_surname"],
       "like_text" : "Nathan Andew",
       "max_query_terms" : 12
    }
  }
}'
