Search in many indices is too slow

ZY2zZ · January 31, 2019, 12:52pm

I try to search in a index,it only spends 9-20ms,But if i search in mutiple indices,it spends a long time(about 110-240ms. Isn't it parallel？ And when i use the profile API,i find that next_doc spents the most time,how can i solve this problem.

How many indices and shards are you querying?

What is the specification of your cluster with respect to nodes, RAM, CPU cores and storage?

Which version are you running?

It's about thirty indices and there are 5 primary shards,no replic shards,version is 5.5.3.
