Hi All,

I'm having trouble with a value\_count aggregation that uses a script. For  
context I have an index of 100,000 dummy documents all with 1-word titles.

My query looks like:

{  
"query": {  
"match\_all": {}  
},  
"filter": {  
"match\_all": {}  
},  
"aggs": {  
"category\_tokens": {  
"value\_count": {  
"script": "doc['title'].values.size() \> 1"  
}  
}  
}

But I get an error like: 'CompileException[[Error: No field found for  
[org.elasticsearch.index.fielddata.ScriptDocValues$Strings@1cdd34b3]'.

If it helps my mapping looks like:

"title": {  
"type": "string"  
}

What am I doing wrong here? Is it not possible to use a script like this?

Hello Sam ,

The title field , i presume is a single value field which means values will  
fail.  
You need to use something like

doc['title'].value.length \> 1

Thanks  
Vineeth
