一、创建索引时，自定义拼音分词和ik分词
PUT /my_index
{
"index": {
"analysis": {
"analyzer": {
"ik_pinyin_analyzer": { 自定义分词name
"type": "custom",
"tokenizer": "ik_smart",
"filter": ["my_pinyin", "word_delimiter"]
},
"pinyin_analyzer": {
"type": "custom",
"tokenizer": "ik_max_word",
"filter": ["my_pinyin", "word_delimiter"]
}
},
"filter": {
"my_pinyin": {
"type" : "pinyin",
"keep_separate_first_letter" : false, 启用该选项时，将保留第一个字母分开，例如：刘德华>l，d，h，默认：false，注意：查询结果也许是太模糊，由于长期过频
"keep_full_pinyin" : true, 当启用该选项，例如：刘德华> [liu，de，hua]，默认值：true
"keep_original" : true, 启用此选项时，也将保留原始输入，默认值：false
"limit_first_letter_length" : 16, 设置first_letter结果的最大长度，默认值：16
"lowercase" : true, 小写非中文字母，默认值：true
"remove_duplicated_term" : true 启用此选项后，将删除重复的术语以保存索引，例如：de的>de，default：false，注意：位置相关的查询可能会受到影响
}
}
}
}
}
二、创建mapping时，设置字段分词(注：相同索引下建不同的type时，相同字段名属性必须设一样)
POST /my_index/user/_mapping
{
"user": {
"properties": {
"id":{
"type":"integer"
},
"userName": {
"type": "text",
"store": "no",
"term_vector": "with_positions_offsets",
"analyzer": "ik_pinyin_analyzer", 自定义分词器name
"boost": 10,
"fielddata" : true,
"fields": {
"raw": {
"type": "keyword" 设置keyword时，对该字段不进行分析
}
}
},
"reason":{
"type": "text",
"store": "no", 字段store为true，这意味着这个field的数据将会被单独存储。这时候，如果你要求返回field1（store：yes），es会分辨出field1已经被存储了，因此不会从_source中加载，而是从field1的存储块中加载。
"term_vector": "with_positions_offsets",
"analyzer": "ik_pinyin_analyzer",
"boost": 10
}
}
}
}
测试
PUT /my_index/user/1
{
"id":1,
"userName":"刘德华",
"reason":"大帅哥"
} PUT /my_index/user/2
{
"id":2,
"userName":"刘德华",
"reason":"中华人民"
}
