Hi there,
in our project we are using hasChild sorting which is exactly by the book:
> ```
> {
> "query": {
> "has_child" : {
> "type" : "blog_tag",
> "score_mode" : "max",
> "query" : {
> "function_score" : {
> "script_score": {
> "script": "_score * doc['click_count'].value"
> }
> }
> }
> }
> }
> }
>
> ```
The problem is that when I have "score\_mode" it returns the following error:
> "reason":{"type":"script\_exception","reason":"failed to run inline script ["\_score \* doc['click\_count'].value] using lang [groovy]","caused\_by":{"type":"missing\_property\_exception","reason":"No such property:
Getting rid of the "score\_mode" will show results that are not sorted. Does anyone have any idea what could be the problem?
Thanks in advance.
Cheers
