由于业务需要使用haschild做关联查询，接口接收查询json串后转换为SearchSourceBuilder，但是提示ParsingException[no [query] registered for [has_child]]
查询json如下：
{

  "from" : 0,

  "size" : 30,

  "query" : {

    "bool" : {

      "should" : [ {

        "multi_match" : {

          "query" : "iphone",

          "fields" : [ "shopName^4.0", "gysName^3.0" ]

        }

      }, {

        "has_child" : {

          "query" : {

            "multi_match" : {

              "query" : "iphone",

              "fields" : [ "skuName^2.0", "brandNameChEn^1.0", "cName" ]

            }

          },

          "type" : "sku"

        }

      } ]

    }

  },

  "highlight" : {

    "pre_tags" : [ "<em>" ],

    "post_tags" : [ "</em>" ],

    "fields" : {

      "shopName" : { }

    }

  }

}

转换代码如下：
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

        try {

            SearchModule searchModule = new SearchModule(Settings.EMPTY, false, Collections.emptyList());

            NamedXContentRegistry registry = new NamedXContentRegistry(searchModule.getNamedXContents());

            XContentParser parser = XContentFactory.xContent(XContentType.JSON).createParser(registry,LoggingDeprecationHandler.INSTANCE,source);

            searchSourceBuilder.parseXContent(parser);

        } catch (Exception e) {

            e.printStackTrace();

            throw SearchException.ES_REMOVE_FAIL.newInstance("解析查询条件异常,source:%s,error:%s",source,e);

        }

        return searchSourceBuilder;
找了一些资料，并查看了源码，发现SearchModule类中并未注册haschildquery类，不知道这种情况如何处理？请帮忙想想办法，多谢！

    以下是SearchModule注册querybuilder的代码，并未有haschildquerybuilder
