Missing doc.score documentation

[Vineeth-Mohan]

I found the variable doc.score very useful but then it don't have documentation in http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-scripting.html , but it has documentation in http://www.elasticsearch.cn/guide/reference/modules/scripting.html .

Kindly add this information.

The score for the current document can be accessed by a script using the _score variable which is equivalent to doc.score. This is the preferred way of accessing the score and is documented at http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-scripting.html#_score

Hello @colings86

ES script - 1.3.2

I am not able to access this field in aggs scripts -
{
"aggs": {
"sum": {
"sum": {
"script": "doc.score"
}
}
}
}

Works

{
"aggs": {
"sum": {
"sum": {
"script": "_score"
}
}
}
}

gives - QueryPhaseExecutionException[[twitter][2]: query[ConstantScore(:)],from[0],size[10]: Query Failed [Failed to execute main query]]; nested: PropertyAccessException[[Error: unresolvable property or identifier: _score] [Near : {... _score ....}] ^ [Line: 1, Column: 1]];

@Vineeth-Mohan it works in groovy, not mvel (which is deprecated)
