ElasticSearch[5.5] 字符串数据类型的 Aggs Range 过滤器

Question

RAM 移动规范中的字段有很多数据，我需要对字符串应用某种范围过滤器。我已将存储桶格式化为键值对 RAM 和 Doc count

 "RAM": {
            "1": 7,
            "32": 1,
            "32 MB": 490,
            "1 GB": 426,
            "2 GB": 361,
            "3 GB": 269,
            "4 GB": 143,
            "512 MB": 136,
            "256 MB": 87,
            "10 MB": 61,
            "64 MB": 47,
            "1 MB": 45,
            "128 MB": 41,
            "56 MB": 27,
            "1.5 GB": 23,
            "16 MB": 12,
            "35 MB": 12,
            "4 MB": 11,
            "0.032 MB": 10,
            "100 MB": 7,
            "3 MB": 7,
            "2 MB": 6,
            "768 MB": 6,
            "40 MB": 4,
            "30 MB": 3,
            "6 GB": 3,
            "20 MB": 2,
            "46 MB": 2,
            "500 MB": 2,
            "60 MB": 2,
            "120 MB": 1,
            "131 MB": 1,
            "138 MB": 1,
            "153 MB": 1,
            "200 MB": 1,
            "24 MB": 1,
            "250 MB": 1,
            "260 MB": 1,
            "50 MB": 1,
            "55 MB": 1,
            "65 MB": 1,
            "8 GB": 1
        }

如何将上面的转换成下面的形式

 128 MB and Below
     1 GB
     2 GB
     3 GB
     4 GB
     6 GB and Above

一种可能的解决方案是将 RAM 的值索引为数字数据类型并在该字段上应用范围过滤器。但是如何区分 1 Mb 和 1 GB 。

Answer 1

我通过转换所有最低单位并删除转换单位来解决它。
