Windows: two fess running without elasticsearch

I have one Fess instance running without elasticsearch on a Windows machine. I want to run a second Fess instance. But it seems both instances using same data. What and where do I have to change something in config to separate them from each other?
Thanks!

  1. Install elasticsearch
  2. Install Fess A which uses the above elasticsearch
  3. Modify index names in fess_config.properties of Fess A
  4. Install Fess B which uses the same elasticsearch
  5. Modify index names in fess_config.properties of Fess B

I modified with a ‘1’ the lines below. Is that correct?

document index

index.document.search.index=fess1.search
