I don't know why mlk can't search for fields that I have set for another tokenizer. Here are my setting and mapping  
The ES version 5.4, IK, and Pinyin plug-ins are all 5.4, jvm1.8

PUT /testcar/  
{  
"index": {  
"analysis": {  
"analyzer": {  
"ik\_pinyin\_analyzer": {  
"type": "custom",  
"tokenizer": "ik\_smart",  
"filter": [  
"my\_pinyin",  
"word\_delimiter"  
]  
},  
"ik\_analyzer": {  
"type": "custom",  
"tokenizer": "ik\_smart",  
"filter": [  
"word\_delimiter"  
]  
}  
},  
"filter": {  
"my\_pinyin": {

```
      "type": "pinyin",
      "keep_separate_first_letter": false,
      "keep_full_pinyin": true,
      "keep_original": true,
      "limit_first_letter_length": 16,
      "lowercase": true,
      "remove_duplicated_term": true
    }
  }
}

```

}  
}  
PUT testcar/secondcar/\_mapping  
{  
"properties": {  
"kilometer": {  
"type": "float"  
},  
"title": {  
"type": "text",  
"fields": {  
"ik": {  
"type": "text",  
"analyzer": "ik\_analyzer"  
},  
"ik\_pinyin": {  
"type": "text",  
"analyzer": "ik\_pinyin\_analyzer"  
}  
}  
}  
}  
}  
PUT testcar/secondcar/1  
{  
"title":"杜卡迪"  
}  
PUT testcar/secondcar/2  
{  
"title":"杜卡迪Monster"  
}  
PUT testcar/secondcar/3  
{  
"title":"杜卡迪Monster 798"  
}  
So you can search for the results  
Query statement：

GET testcar/\_search  
{  
"query": {  
"more\_like\_this": {  
"fields": [  
"title.ik\_pinyin"  
],  
"like": "杜卡迪",  
"min\_term\_freq": 1,  
"max\_query\_terms": 12,  
"analyzer": "ik\_pinyin\_analyzer"  
}  
}  
}  
But that won't do  
Query statement：

GET testcar/\_search  
{  
"query": {  
"more\_like\_this": {  
"fields": [  
"title.ik"  
],  
"like": "杜卡迪",  
"min\_term\_freq": 1,  
"max\_query\_terms": 12,  
"analyzer": "ik\_pinyin\_analyzer"  
}  
}  
}  
Please God advice  
Please God advice  
Please God advice
