Binarylogic Searchlogic

I found something it's not working (or maybe i'm doing it wrong)

The controller:

@search = PerformanceLog.new_search(params[:search])
@search.select = 'url, server, MIN(tiempo) AS minimo, MAX(tiempo) AS maximo, AVG(tiempo) AS promedio, COUNT(*) AS apariciones'
@search.group = 'url, server'
@search.order = 'COUNT(*) DESC'
@search.conditions.case_log.suite_log.environment ||= "PRODUCCION"
@search.per_page = nil
@perf_logs = @search.all

and i get this query :

SELECT performance_logs.* FROM performance_logs LEFT OUTER JOIN case_logs ON case_logs.id = performance_logs.case_log_id LEFT OUTER JOIN suite_logs ON suite_logs.id = case_logs.suite_log_id WHERE (suite_logs.environment= 'PRODUCCION') GROUP BY url, server ORDER BY COUNT(*) DESC

The conditions, gruoping and ordering are ok, but I can't get the columns I want.

Using User.find(:all, :select => 'url, server, MIN(tiempo) AS minimo, MAX(tiempo) AS maximo, AVG(tiempo) AS promedio, COUNT(*) AS apariciones')

It gets the attributes I want, but I can't use the searchlogic conditions.

Is there anyway to fix this?

I'm using MySQL database in a debian machine and the Rails app is hosted in a Windows machine (I'm going to migrate it soon to a linux box :) )
