Hi

I am trying to access document fields in the script based sorting

curl -XPOST '[http://localhost:9200/users/user/\_search](http://localhost:9200/users/user/_search)' -d '{  
"query" : { "term" : { "group" : "dpe" }},  
"sort" : { "\_script" : { "script" : "doc['first\_name'].stringValue",  
"type" : "string", "order" : "asc"}}  
}'

and I get following exception

nested: ElasticSearchIllegalArgumentException[No field found for  
[org.elasticsearch.index.field.data.strings.StringDocFieldData@2ad6d4be]]

I get this error if I try to accessing document fields using  
doc['field\_name'].stringValue. I am able to access values by using  
doc.field\_name syntax though.

Thanks  
Harish

Its because of curl and the use of ' (which is used after -d as well).
