Hello,  
I am trying to decrease the size of my index.  
I saw that the nvd files are used for norms and boost factors.  
I have no need for ranking in my cluster, is it possible to change index/cluster definitions to reduce or cancel those files?  
I already tried using "norms:" {enabled: "false"} but it had only a small impact on the index size…  
If you have any other ideas for decreasing the index volume please let me know.  
Regards,  
Ben.

You could try setting the fields to not indexed.

I still need to use the search utilities but I don't need the ranking .  
I already tried the following:

1. Mapping definitions:  
Doc\_values : false (if possible)  
include\_in\_all: false (if possible)  
not\_analyzed: false (if possible)
2. Optimize (didn't help for large indexes only small indexes)
3. Compress with best compression (deflate)
