Try to create an index with a field that is not analyzed in order to perform a string search. But when I try to create the index it generates errors.

In this way I create the index:

PUT / contents  
{

"mappings": {

"category": {

"\_all": {"enabled": false},

"\_source": {"compressed": true},

"properties": {

"name": {"type": "text", "index": "analyzed"}

}

}

}

}

and it generates me error:

{  
"error": {  
"root\_cause": [  
{  
"type": "mapper\_parsing\_exception",  
"reason": "Failed to parse mapping [category]: Could not convert [name.index] to boolean"  
}  
],  
"type": "mapper\_parsing\_exception",  
"reason": "Failed to parse mapping [category]: Could not convert [name.index] to boolean",  
"caused\_by": {  
"type": "illegal\_argument\_exception",  
"reason": "Could not convert [name.index] to boolean",  
"caused\_by": {  
"type": "illegal\_argument\_exception",  
"reason": "Failed to parse value [analyzed] as only [true] or [false] are allowed."  
}  
}  
},  
"status": 400  
}

How it should create that certain fields are not analyzed so you can search the text strings.

Hi, since Elasticsearch version 5.x, you can use the `keyword` datatype for not analysed strings ([https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html)).
