Replicas in memory. How disable?

Hi All!
I want to know if there is an option to disable storing replicas in RAM? Maybe it helps with no-knn search (e.g. keyword search), but with k-NN it does not speed up but also takes up twice as much space (1 replica) in RAM! Replicas are needed in case of disconnection data-node. Can you help me? Thanks for reply!

Hi @doc113, I am not sure if this can be done. I think you might be able to try setting the preference setting in your queries or use some kind of custom routing.
