Question

我收集了文档用户

User
{
  "Status": "ACTIVE",
  "Login": {
    "UserName": "login",
    "Password": null,
    "CreationDate": "2011-12-07T11:30:24.4062500Z",
    "Roles": [
      {
        "Id": "roles/WebUser",
        "Name": "WebUser"
      },
      {
        "Id": "roles/Admin",
        "Name": "Admin"
      }
    ]
  },
}

我如何进行查询以获取角色名称为“WebUser”的用户列表，但角色名称为“Admin”的用户除外（包含角色“WebUser”但不包含角色“Admin”）

使用LINQ或lucene

Answer 1

您需要为此创建索引，例如：

from user in docs.Users
select new { Roles = user.Logins.Roles.Select(x=>x.Name) }

然后你可以查询使用：

Roles:WebMaster AND -Roles:Admin

Answer 2

这是你想要的吗？

var users = documentSession.Query<User>()
    .Where(x => x.Login.Roles.Any(y => y.Name == "WebUser"))
    .Where(x => x.Login.Roles.Any(y => y.Name != "Admin"))
    .ToList();
