Hi All,

I am indexing 5000 Docs/sec.  
I've a problem with search query that it consumes 100% of CPU when I do search with Kibana. its size 30 GB and have more that 1 Billion docs inside.  
System Configuration: 16 GB RAM  
ES\_HEAP\_SIZE=3g  
ES\_MIN\_MEM=3g  
ES\_MAX\_MEM=3g

Index Setting:

index.number\_of\_shards: 8  
index.number\_of\_replicas: 1

I do some experiment with Segment also but i am still stuck.  
Please suggest me i need to do something with Segment.

Thanks,  
Sumit Gupta
