i am new in elasticsearch world , i wanna build a project with elastic stack but i don 't know what to use ! I need to perform calculation using multiple fields from multiple indexes then reuse those results in kibana dashboard.
I am asking what to use ?
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 ???
thank ypu for your reply
