elasticsearch - ElasticSearch完成建议程序-不返回数据

Question

您能用ElasticSearch建议我吗？
https://www.elastic.co/guide/en/elasticsearch/reference/5.1/search-suggesters-completion.html

我已经在ES索引

中创建了类型

curl -XPUT'本地主机:9200 / tass_suggest_test / _mapping / company？pretty'-H'内容类型:application / json'-d'

{
   "company": {
            "properties": {
                "id": {
                    "type": "integer"
                },
                "inn": {
                    "type": "keyword"
                },
                "innSuggest" : {
                    "type" : "completion"
                }
            }
        }
}
'

用一些数据填充它

现在我尝试获取数据

curl -XGET' http://localhost:9200/tass_suggest_test/company/_search?pretty'-d'

{
    "from" : 0, "size" : 1,
    "query" : { 
        "wildcard" : { "inn" : "78200*" }
    }
}'

没关系，我有一些数据:

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 10,
    "successful" : 10,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "tass_suggest_test",
        "_type" : "company",
        "_id" : "23515589",
        "_score" : 1.0,
        "_source" : {
          "id" : 23515589,
          "inn" : "7820056885",
          "innSuggest" : "7820056885"
        }
      }
    ]
  }
}

但是当我尝试建议查询时，我什么也没得到

curl -XGET 'localhost:9200/tass_suggest_test/_suggest?pretty' -H 'Content-Type: application/json' -d'
{
    "company-suggest" : {
        "prefix" : "78200",
        "completion" : {
            "field" : "innSuggest"
        }
    }
}
'

{
  "_shards" : {
    "total" : 10,
    "successful" : 10,
    "failed" : 0
  },
  "company-suggest" : [
    {
      "text" : "7820056885",
      "offset" : 0,
      "length" : 10,
      "options" : [ ]
    }
  ]
}

我的错在哪里

默认情况下，完成建议程序使用简单分析器，因此从输入字段中删除了数字。如果要保留数字，可以使用建议字段的空白分析器:

{
   "company": {
            "properties": {
                "id": {
                    "type": "integer"
                },
                "inn": {
                    "type": "keyword"
                },
                "innSuggest" : {
                    "type" : "completion",
                    "analyzer": "whitespace"
                }
            }
        }
}
