I think the white space after the comma is the culprit. No white space is allowed in function queries that are embedded, such as in the sort parameter.

Hi,


Why did you use upper case? What happens when you use : sort=sum(...

Gora,
firstly I would like thank you for your quick response.

.../select?q=MacBook&sort=SUM(base_score, score)+desc&wt=json&indent=true

I tried that but it didn't work and I got this error message

"error":{
   "msg":"Can't determine a Sort Order (asc or desc) in sort spec
'SUM(base_score, score) desc', pos=15",
   "code":400}}

Best Regards,
Chun
