Parent doesnt show records of children in filter

I am using the filter module as the main search for cobalt. I have a parent category with many children. When the parent category is selected in the filter I want all of the children records to appear, however I can't make this happen.

This is possible only when you browse category. When you navigate to it from category index. This is where Records mode is applied.

But when you use category as filter, it finds records only in particular category you navigated to but not the one you selected in filters.

In other words, category filter make sense only if Filter mode is though whole section.

I see. Thanks for the reply. I will need to try and figure out another way to do my Search.

Not sure if I got the whole idea...

All your articles are in the parent-category, too?

This parent category is one of many parent categories? Or is there one root section?

I have a section called 'Directory' with categoroies that make up the different departments. Ex. Biology, Physics, Math. However sometimes a category like 'Math' might have children categories like 'Tenured Faculy', Part-time faculty, etc...

The problem is then that if you select Math from the dropdown menu it doesn't show everyone in the sub-categories. It only shows the people select in the parent category of 'Math'. Multiple categories is one solution, but I can't rely on all my users to do this.
