doubts about query

Hi, I am new in this django, but I have already tried a few examples
I found on the web, but I have some doubts and queries:

Given the following classes:

Book class (models.Model):
Models.ForeignKey author = (Author)
Models.ForeignKey publisher = (Editor)
Publicaction = models.DateTimeField = ()
Pages = models.IntegerField pages = ()

Author class (models.Model):
Name = models.CharField (...)
Nationality = models.CharField (...)

Editor class (models.Model):
Name = models.CharField (...)
Country = models.CharField (...)

As could perform the following query:

All books were published between 2005-2007, whose author
Be "Juan Perez" and belongs to a publisher whose country is "Spain"
