Question

I have collection of documents Users

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"
      }
    ]
  },
}

How can i make a query to get list of users with role name “WebUser” except users with role name “Admin” (Contains role “WebUser” but not contains role “Admin”)

Using LINQ or lucene

Answer 1

You need to create an index for that, something like:

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

And then you can query is using:

Roles:WebMaster AND -Roles:Admin
