Hi ,  
I am looking for a way by which we can add value of a field already indexed with value of same field from new updated document to be indexed.  
for e.g.  
version 1 document:  
{  
"\_index" : "test\_index",  
"\_type" : "\_doc",  
"\_id" : "1",  
"\_version" : 1,  
"\_score" : 0.2876821,  
"\_source" : {  
"TRANSACTIONTYPE" : 12,  
"ISCORRELATED" : "1",  
"MOBILENUMBER" : "9765451087"  
}  
}

version 2 document:  
{  
"\_index" : "test\_index",  
"\_type" : "\_doc",  
"\_id" : "1",  
"\_version" : 2,  
"\_score" : 0.2876821,  
"\_source" : {  
"TRANSACTIONTYPE" : 10,  
"ISCORRELATED" : "1",  
"MOBILENUMBER" : "9765451087"  
}  
}

So after indexing version 2 document, TRANSACTIONTYPE should have 10 + 12 = 22 value. Any suggestions/help would be great.
