I need to perform aggregations on multiple index through Java.

```
RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost",9200,"http")));
		
		SearchRequest searchRequest = new SearchRequest();
		SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
		searchSourceBuilder.query(QueryBuilders.matchAllQuery()).aggregation(AggregationBuilders.avg("expenditure_avg").field("expenditure"));
		searchRequest.source(searchSourceBuilder);
		SearchResponse searchResponse = client.search(searchRequest);
	
		
		System.out.println(searchResponse.toString());

```

I have tried the above but dont know how to perform the same on multiple Index.

From the code you pasted, you are already running that on all indices.
