Hi  
I have 2 indexes with following names  
Cloudfront  
cfID  
Status  
Domain and ....  
ExtraLoggingCloudfront  
cfID  
extraHeaderCheck1  
extraHeaderCheck2

In the 2 indexes i have different fields but there is 1 field which is same cfID

I want to merge this to indexes and add that 2 - "extraHeaderCheck1" and "extraHeaderCheck2" to cloudfront logs how i should do this what are the options
