Per ES document, we can configure similarity on a field in mapping setting like this:

{  
"book" : {  
"properties" : {  
"title" : { "type" : "string", "similarity" : "my\_similarity" }  
}  
}

Is this possible to configure the similarity on index or type level so that don't have to configure the similarity for each field one by one?
