ElasticSearch完成提示-不返回数据

Question

你能帮我做一下ElasticSearch吗？建议:https://www.elastic.co/guide/en/ElasticSearch/reference/5.1/search-suggesters-completion.html

1. 我在ES索引中创建了类型

curl-xput“localhost:9200/tass_suggest_test/_mapping/company？pretty”-h“content-type：application/json”-d“

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

填充了一些数据

curl-xget“http://localhost:9200/tass_suggest_test/company/_search？pretty”-d“

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

没事，我得到了一些数据：

{
  "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"
        }
      }
    ]
  }
}

但当我尝试建议查询时，我什么也没有得到

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？

完成提示器默认使用简单分析器，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格分析器：

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