I want to get all values of a field from elasticsearch using java high level client.

I'm using following code:

SearchRequest searchRequest =  new SearchRequest(index);
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(QueryBuilders.termQuery(field, "*"));
searchRequest.source(sourceBuilder);
SearchResponse response = client.search(searchRequest, RequestOptions.DEFAULT);

I want to get the values DISTINCT (like select distinct field from table), if it's possible.

Fairly straight forward, use aggregations, refer: https://kb.objectrocket.com/elasticsearch/how-to-get-unique-values-for-a-field-in-elasticsearch for an example. – Ironluca Mar 12 '20 at 10:51
Thanks for your reply. It works with aggregations. – blademountain Mar 16 '20 at 12:51
