Hi All,

I am facing an issue with elastic search, but not able to fix it for last two days.

I have a document product with a field list dynamicAttributes.  
e.g.  
dynamicAttributeValues": [  
"S",  
"Blue Ridge",  
"10.5",  
"10",  
"11.5",  
"11.5",  
"6.5",  
"6",  
"5",  
"5.5",  
"Large",  
"XLarge"  
]

I want to aggregate the result with doc\_count which I am able to do. But the weird thing I noticed that **terms aggregation is skipping the dot('.') character** as the aggregation coming as below  
{  
"size": "65",  
"count": 15437  
},  
{  
"size": "13",  
"count": 10679  
},  
{  
"size": "105",  
"count": 9651  
},  
{  
"size": "55",  
"count": 9359  
}

we are getting 65 instead of 6.5, 105 instead of 10.5.... !!!!!

I googled, binged and searched everywhere but couldn't get a resolution to this.

## Please help on this

Thanks  
Jithin Kuriakose

The issue is actually with the mapping, not necessarily the terms aggregation. Terms aggs work on the post-analysis form of the the field. So in this case, the field likely has an analyzer that tokenizes on special characters (`standard` analyzer does this). So when `5.5` is tokenized by the analyzer, it gets turned into `["5", "5"]` instead of `"5.5"`.

So when the terms agg starts working on the data, it is seeing `"5"` individually and the periods are lost.

The solution is to map your field as a `keyword` instead of `text`. Keyword fields are not analyzed, so the token being aggregated is identical to the original token.

`text` fields are more for search, `keyword` more for aggs. Generally 🙂

Hi @polyfractal,  
Thanks for your response.  
The actual issue seems to be different for me.  
I have added a new multi raw field, which is not analyzed. Now I am aggregating on productSkuDynamicAttributeValues.raw field  
But still there are still some problems.

Below are my new mapping on the field.  
"productSkuDynamicAttributeValues": {  
"type": "string",  
"fields": {  
"high\_precision": {  
"type": "string",  
"analyzer": "high\_precision\_analyzer"  
},  
"raw": {  
"type": "string",  
"index": "not\_analyzed"  
},  
"word\_proximity": {  
"type": "string",  
"analyzer": "word\_proximity\_analyzer"  
}  
},  
"analyzer": "high\_recall\_analyzer"  
},

I have a value "0-6 months", but in aggregation I am getting "06"... !!!!

Could you please help me on this?

Thanks  
Jithin
