Question

我对facet术语查询有一些问题（使用ElasticSearch 1.7.0），所有浮点值都存储在数据库和elasticsearch体积中，但是当我请求数据时，我得到的值就像那样＆＃ 34; 2.99000000954＆＃34;

奇怪的是，当我向＆＃34; 2.99000000954＆＃34;提出请求时，引擎找到了与此数据相关的好文章，该文章带有＆＃34; 2.99＆＃34;值。

请查看以下代码文件和卷曲呼叫请求：

映射（来自_plugin / head）

"pvi": {
    "include_in_all": false,
    "type": "float",
    "fields": {
        "raw": {
            "type": "float"
        },
        "sort": {
            "type": "float"
        }
    }
}

elastic_bulk_Article_en_XXX.json0

{
  "pvi": [
    "2.99"
  ],
}

卷曲调用

curl -XGET 'http://elasticsearch:9200/entrepriseName_search_index_fr_fr/Article/_search' -d '{"query":{"filtered":{"query":{"match_all":{}},"filter":[]}},"aggs":{"pvi":{"filter":{"query":{"query_string":{"query":"*","fuzzy_prefix_length":1,"fields":["pvi"]}}},"aggs":{"pvi":{"terms":{"field":"pvi","size":25,"order":{"_term":"asc"}}}}}},"size":0}'

卷曲调用结果
