Demonstrating various searches in mongomapper

message_log.rb

class MessageLog
   include MongoMapper::Document

   # Attributes ::::::::::::::::::::::::::::::::::::::::::::::::::::::
   key :repeat_count, Integer, :default => 0
   key :patient_name, String, :default => 'Unknown', :index => true
   key :patient_num, String, :default => 'Unknown', :index => true
   key :patient_emr, String, :default => 'Unknown', :index => true
   # Doctor info (number, name, group)
   key :doctor, String, :default => 'Unknown', :index => true
   ...
   # Scopes :::::::::::::::::::::::::::::::::::::::::::::::::::::
   scope :by_emr, lambda {|emr| where(:patient_emr => emr)}
end

message_logs_controller.rb

And searches like this in the controller that allow numbers as text
(from a UI search form):
...
   def search
    @message_logs = nil
    case params[:type]
      when "name"
        @message_logs = MessageLog.paginate( :page =>params[:page],
'$where' => "function() { return
this.patient.match(/#{params[:finder]}/i); }")
      when "patient_num"
        @message_logs = MessageLog.paginate(:patient_num =>
params[:finder], :page =>params[:page])
      when "emr_num"
        @message_logs = MessageLog.by_emr(params[:finder], :page
=>params[:page]).paginate
      when "doctor"
        @message_logs = MessageLog.paginate( :page =>params[:page],
'$where' => "function() { return
this.doctor.match(/#{params[:finder]}/i); }")
      when "control_id"
        @message_logs = MessageLog.paginate( :control_id =>
params[:finder], :page =>params[:page])
    end
   end
...

And for the stats, I search with a straight-up number:
@num_repeated = MessageLog.count( :repeat_count.gt => 0)
