Pls Can u help me with how can I index this nested data using java via hashmap..
Create your pojo classes with nested datatypes and use Jackson databind apis or google gson
how to apply time interval
good question, so to apply time interval use range query , in blog example instead of using QueryBuilders.matchQuery you may use QueryBuilders.rangeQuery for example QueryBuilders.rangeQuery("field").gte("2022-01-05").lte("2022-01-06")
Bro plz share some code on elasticsearch, how to find distinct values on multiple fields by hashing it using script api in elasticsearch
Plz help bro...
