To do which part exactly?  
Kibana can definitely query the data and then perform some calculations, but unless you describe what they are we can't help 🙂

thank you for yor reply .  
In fact i need to extract some results from my data which is divided in many indexes. for more details , i have many indexes and i only need to perform calculations with many fields of these indexes then visualize the results with kibana.  
I discovered that i can use alias to work with multiple indexes and expression and painless to perform calculations.  
am i on the right path ???
