Use it like this：

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(QueryBuilders.matchQuery("text", "elastic"));
CollapseBuilder sb=new CollapseBuilder("firstField");
InnerHitBuilder ib =new InnerHitBuilder("secondField");
sb.setInnerHits(ib);
searchSourceBuilder.collapse(sb);
