Hi,

I have a project model which has a filter:

has paid, :type => :boolean

If paid checkbox is flagged, sphinx searches for paying projects. the
problem is that some projects have not any course:

project.courses.count # returns 0

I there a way to search for paying projects having at least one
course?

 paid => true and projects.courses.count > 0

at the moment I have paid sent in the conditions

A solution could be to add a field set to true if its courses are more
than zero, but it is a redundant information
