我刚刚特意写的,用2个Map作为传参,一个是must,一个是should。代码如下: //创建查询SearchRequestBuilder srb = client.prepareSearch(INDEX);srb.setTypes(ASK_TYPE);srb.setSearchType(SearchType.DFS_QUERY_THEN_FETCH);//分页srb.setFrom...

/** * Constructs a new search source builder with a raw search query. */ public SearchRequestBuilder setQuery(String query) { sourceBuilder().query(query); return this; }
