how to viewAll the docs of an index using rest in elasticsearch

Question

while creating a rest which function can i use to view all the documents in an index, like for prepareGet takes 3 arguments (indexName, type, id) to view the document, i need to know a function which takes only one argument as indexName and displays all the data in that particular index

In absolute terms, can you provide a count? is it 100, 1000, 10000, 1M, ...? — Val, Oct 05 '18 at 11:35

If your index only contains a few documents (100-150), then you can get all of them in a single search using the _search endpoint with a size parameter that is bigger than the number of your documents:

GET your-index/_search?size=1000

Using the Java HighLevel REST client, you can do it like this:

SearchRequest searchRequest = new SearchRequest("your-index"); 
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder(); 
searchSourceBuilder.query(QueryBuilders.matchAllQuery()); 
sourceBuilder.from(0); 
sourceBuilder.size(1000); 
searchRequest.source(searchSourceBuilder); 
SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

This is the REST API call. Do you mean the Java HighLevel REST client? – Val Oct 05 '18 at 12:07
