I have a view that displays teasers of content type X (across all topics). Under each teaser, I would like to display links to instances of content type Y that share the topic (taxonomy) of that teaser. This seems like it should be relatively simple, but I'm having a hard time relating the filter criteria to the taxonomy of each line of the View's output rather than the taxonomy of the whole View page.
You can use the Views Field View module to do the trick: https://drupal.org/project/views_field_view
