Greetings!  
My document consist of the fields: "abc","def" and "xyz".  
I had created a scripted field called ' **adding**' to add the value of the field "abc"and "def" within a document,  
doc['abc'].value+doc['def'].value

I would like to obtain the **sum of the documents**' **adding**', then this value **divide** by **sum of documents** field "xyz". Is there any possibility to do that?  
Thank you.
