如何通过在Ruby on Rails中进行查询来在数据库中进行搜索？

Question

i am using rails and mongo db as database simply i want to search I have a field name role Now i send the search item in

params[:role]
params[:name]

Now i have the model User now what could be my query to search the data in the User model like params[:name] I did like

 @role = params[:role]
    @name = params[:name] 
     @data = User.{where(:role => @role)}.where("description LIKE (?)",
    "%#   {@name}%").desc(:created_at).
    excludes(:id    => current_user.id)

Above query is just analysis. I mean to say it should like in therotical but i didnt get id.

Does this work? (from my head...)

 @role = params[:role]
 @name = params[:name] 
 @users = User.where(:role => @role)
 @data = @users.where(users[:description].matches("%#{@name}%")).order("created_at desc").excludes(:id=> current_user.id)
