Hi! I'm pretty new with elastic search and now exploring custom-routing, so I need a piece of advice. I need to create an index which will contain a field clientID and some related data with it. I want to create a custom route based on its clientID like doing a modulus operation with 7 on clientID and create a route with the outcome of modulus operation but the problem is clientID is a mongoID type field. So What can I do in that case?  
Any suggestions will be appreciated and please let me know If you something didn't add up right in my question.
