4.3 测试IK中文分词器的基本功能

（1）ik_smart 
其中pretty本意”漂亮的”，表示以美观的形式打印出JSON格式响应。

GET _analyze?pretty

{

  "analyzer": "ik_smart",

  "text":"安徽省长江流域"

}

分词结果

{

  "tokens": [ { "token": "安徽省", "start_offset": 0, "end_offset": 3, "type": "CN_WORD", "position": 0 }, { "token": "长江流域", "start_offset": 3, "end_offset": 7, "type": "CN_WORD", "position": 1 } ] }

 
（2）ik_max_word

GET _analyze?pretty

{

  "analyzer": "ik_max_word",

  "text":"安徽省长江流域"

}

分词结果

{

  "tokens": [ { "token": "安徽省", "start_offset": 0, "end_offset": 3, "type": "CN_WORD", "position": 0 }, { "token": "安徽", "start_offset": 0, "end_offset": 2, "type": "CN_WORD", "position": 1 }, { "token": "省长", "start_offset": 2, "end_offset": 4, "type": "CN_WORD", "position": 2 }, { "token": "长江流域", "start_offset": 3, "end_offset": 7, "type": "CN_WORD", "position": 3 }, { "token": "长江", "start_offset": 3, "end_offset": 5, "type": "CN_WORD", "position": 4 }, { "token": "江流", "start_offset": 4, "end_offset": 6, "type": "CN_WORD", "position": 5 }, { "token": "流域", "start_offset": 5, "end_offset": 7, "type": "CN_WORD", "position": 6 } ] }

（3）新词

GET _analyze?pretty

{

  "analyzer": "ik_smart",

  "text": "王者荣耀"

}

分词结果

{

  "tokens": [ { "token": "王者", "start_offset": 0, "end_offset": 2, "type": "CN_WORD", "position": 0 }, { "token": "荣耀", "start_offset": 2, "end_offset": 4, "type": "CN_WORD", "position": 1 } ] }

4.4 扩展字典

（1）查看已有词典

[es@node1 analysis-ik]$ pwd

（2）自定义词典

[es@node1 analysis-ik]$ mkdir custom

[es@node1 analysis-ik]$ vi custom/new_word.dic

[es@node1 analysis-ik]$ cat custom/new_word.dic
