service-some-2021-11-21
service-some-2021-11-22
servoce-some-2021-11-23

Now you need to query one of the four documents json attribute .

resolvent

The solution is very simple , This is what ES The power of , If you fill in when looking up a document source Parameter is service-some-2021-11-20 Words , Now there is no need to change anywhere else , Just fill in a wildcard ,service-some-*.

Of course , If you want to query all the documents of a month, it is service-some-2021-11-*
