sort by a copy field error

[Pedro Figueiredo]

Hello,

 

I have a pretty basic question:  how can I sort by a copyfield?

 

My schema conf is:

 

<field name="name" type="text_general_edge_ngram" indexed="true"
stored="true" omitNorms="true" termVectors="true"/>

<field name="name_sort" type="string" indexed="true" stored="false"/>

<copyField source="name" dest="name_sort" />  

 

And when I try to sort by "name_sort" the following error is raised: 

"error": {

    "msg": "sort param field can't be found: name_sort",

    "code": 400

  }

 

Thanks in advanced,
