i call the /{index}/\_stats/ interface two times, and try to compute average search cost time use:

（total.search.query\_time\_in\_millis 2 - total.search.query\_time\_in\_millis 1）/ ( total.search.query\_total 2 - total.search.query\_total 1)  
+  
（total.search.fetch\_time\_in\_millis 2 - total.search.fetch\_time\_in\_millis 1）/ ( total.search.fetch\_total 2 - total.search.fetch\_total 1)

however find query + fetch is only 0.1ms, this is much smaller than the Request Time in Kibana (6ms) which i think is right.

how can i compute average search request cost time through indices stats api ?
