请问一下关于ik分词器分词内容中文和数字混合时无法分出数字有没有解决办法

我在ES6.2.2上安装的原生elasticsearch_ik，没有扩展词典：
和你一样的检索匹配如下,

{

  "tokens": [

    {

      "token": "恒",

      "start_offset": 0,

      "end_offset": 1,

      "type": "CN_CHAR",

      "position": 0

    },

    {

      "token": "大",

      "start_offset": 1,

      "end_offset": 2,

      "type": "CN_CHAR",

      "position": 1

    },

    {

      "token": "积分",

      "start_offset": 2,

      "end_offset": 4,

      "type": "CN_WORD",

      "position": 2

    },

    {

      "token": "2018",

      "start_offset": 4,

      "end_offset": 8,

      "type": "ARABIC",

      "position": 3

    }

  ]

}

如上，并且不论是粗粒度还是细粒度都包含的。
 
更进一步如果你想完全匹配可以通过"match_phrase”短语匹配实现。

es5.5.3，没发现你这问题

{

  "tokens": [

    {

      "token": "恒",

      "start_offset": 0,

      "end_offset": 1,

      "type": "CN_CHAR",

      "position": 0

    },

    {

      "token": "大",

      "start_offset": 1,

      "end_offset": 2,

      "type": "CN_CHAR",

      "position": 1

    },

    {

      "token": "积分",

      "start_offset": 2,

      "end_offset": 4,

      "type": "CN_WORD",

      "position": 2

    },

    {

      "token": "2018",

      "start_offset": 4,

      "end_offset": 8,

      "type": "ARABIC",

      "position": 3

    }

  ]

}

尝试下细粒度分词ik_max_word
