Question

我尝试转换此代码块但无法找到要更换的正确定义。已过滤接受操作＆lt; FilteredQueryDescriptor＆LT; T>＆gt;选择。我已升级到NEST版本5.5.0，这是我尝试使用更高版本的NEST转换为工作的代码块：

        UserView defaultUserView = new UserView();

        SearchDescriptor<MyOrder> _searchDesc = new SearchDescriptor<MyOrder>();

        _searchDesc = _searchDesc                    
                .Index(MyIndex)
                .Type(MyType)
                .Query(mq => mq.Filtered(QueryDescriptor(defaultView)))
                .SearchType(SearchType.Count)

这是QueryDescriptor：

    private Func<SearchDescriptor<MyOrder>, SearchDescriptor<MyOrder>> QueryDescriptor(UserView userView)
    {
        Func<SearchDescriptor<MyOrder>, SearchDescriptor<MyOrder>> result;

        result = delegate(SearchDescriptor<MyOrder> descriptor)
        {
            descriptor.Query
            (
                query => query.MatchAll()
            )
            .Query(f => f.Bool(CommonHelper.GetFilters(userView)));
            return descriptor;
        };

        return result;
    }

编辑：这是CommonHelper.GetFilters（userView）：

 public static class CommonHelper
 {
    public static Func<BoolQueryDescriptor<MyOrder>, BoolQueryDescriptor<MyOrder>> GetFilters(UserView userView)
    {
       Func<BoolQueryDescriptor<MyOrder>, BoolQueryDescriptor<MyOrder>> 
       result= delegate (BoolQueryDescriptor<MyOrder> descriptor)
         { 
             switch (userView.UserView)
             {
                  case UserView.1:
                       descriptor.Must(OldDefaultFilter());
                       break;
                  case UserView.2:
                       descriptor.Must(OldDefaultFilter())
                              .MustNot(MustNotDefaultFilter());
                       break;
             }
             return descriptor;
          };
        return result;

} }

Answer 1

FilteredQueryDescriptor<T>在NEST 2.x中已弃用，并已在NEST 5.x中删除，与各个主要版本中Elasticsearch的更改一致。

继续前进，使用bool查询而不是查询的must子句和过滤器的filter子句。

替换为NEST 5.5.0中的.Filtered
