如何在Expression.Or中设置多于2个表达式

Question

我想创建一个超过3-4 Expression.Or的查询？但Expression.Or只是让我在其中添加两个表达式.

if (!string.IsNullOrEmpty(keyword))
                query
                    .Add(Expression.Or(
                             Expression.Like("Name", keyword, MatchMode.Anywhere),
                             Expression.Like("LastName", keyword, MatchMode.Anywhere)))
                    .Add(Expression.Or(
                             Expression.Like("Email1", keyword, MatchMode.Anywhere),
                             Expression.Like("Email2", keyword, MatchMode.Anywhere)));

上面的代码生成"名称像%this this或LastName like%this%AND Email1 like%this%和Email2 like%this.

提前致谢.

使用Disjunction而不是Or.
