I've got 2 levels of taxonomy terms attached to a node type allowing multiple selections. If a specific node doesn't have the parent term selected and only a child selected the pager won't display.
I'm using a view to handle multiple loads of news types and categories with a few arguments.
Arguments
Taxonomy: Term ID (with depth)
Taxonomy: Term ID depth modifier
Taxonomy: Term ID
Filters
Node: Type = News
This is just default custom pagers settings, with selected node types and views selection.
