elasticsearch java API搜索多個index和type

代碼以下，一看便知

SearchResponse response = client.prepareSearch("index1", "index2")
        .setTypes("type1", "type2")
        .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
        .setQuery(QueryBuilders.termQuery("multi", "test"))                 // Query
        .setPostFilter(QueryBuilders.rangeQuery("age").from(12).to(18))     // Filter
        .setFrom(0).setSize(60).setExplain(true)
        .get();

index1,index2;

type1,type2.
