Recently, I have built an ELK system, I wat to set the type of some fields to 'keyword' by ES mapping , but it doesn't work.Here is my ES mapping :  
PUT /\_template/francis-template  
{  
"index\_patterns": ["_"],  
"version" : 60001,  
"order": "10",  
"settings": {  
"index": {  
"number\_of\_shards": "1",  
"number\_of\_replicas": "0",  
"refresh\_interval": "10s"  
}  
},  
"mappings": {  
"dynamic\_templates": [  
{  
"string\_fields": {  
"match": "_",  
"match\_mapping\_type": "string",  
"mapping": {  
"type": "keyword"  
}  
}  
},  
{  
"dates": {  
"match": "\*Time",  
"match\_mapping\_type": "string",  
"mapping": {  
"type": "date",  
"format": "yyyy-MM-dd HH:mm:ss.SSS"  
}  
}  
},  
{  
"dates": {  
"match": "\*Date",  
"match\_mapping\_type": "string",  
"mapping": {  
"type": "date",  
"format": "yyyy-MM-dd HH:mm:ss.SSS"  
}  
}  
}  
],  
"properties": {  
"@timestamp": {  
"type": "date"  
},  
"appName": {  
"type": "keyword"  
},  
"className": {  
"type": "keyword"  
},  
"exportable": {  
"type": "keyword"  
},  
"logLevel": {  
"type": "keyword"  
},  
"message": {  
"type": "keyword"  
},  
"parentId": {  
"type": "keyword"  
},  
"pid": {  
"type": "keyword"  
},  
"spanId": {  
"type": "keyword"  
},  
"thread": {  
"type": "keyword"  
},  
"traceId": {  
"type": "keyword"  
}  
}  
}  
}  
}

after put the mapping , I deleted all the indexes and then created a new index, when I cliked the new index's mapping , I found my settings doesn't work. Here is the screen shot :

@francis-oyc,

updating the type of fields is not possible, since all existing data would not be indexed in the way reflected by the new type.

Instead you would have to [reindex](https://www.elastic.co/guide/en/elasticsearch/reference/7.1/docs-reindex.html) your data to a new index with the corrected mapping.

Notice that text data is by default indexed both as text and keyword, thus you can use the `appName.keyword` field for an exact match keyword query.

If I don't want to reindex my data to a new index ，when I set the output properties for Logstash ，could I specify a custom template to overrite the default template ？And does it work？

My step is : First， I put the mapping in Kibana. Second， I deleted all existing indexes，and then created a new index. So I don't think there's any data existed. My purpose is : Logs outputted from Logstash to Elasticsearch，index mapping would be created according to the type that I set，but it's not.
