Question about value_count aggregation

Elastic Stack Elasticsearch
1

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
