[support] node reference pulling cck fields and taxonomy terms

I'd like to do the following and curious if there's a module or common practice that can accomplish this.

I have parent (called Publication) and child (called Dataset) content types. Each Publication node has one or more children Dataset nodes. I'm using nodereference to associate them. Of course, there are several tax terms and CCK fields.they have in common. Can I pull these values from the referenced node? If "pulling" is not quite the way to go, can I display and search on the fields in the referenced node?

When I display a Dataset node, I want to show several fields/terms from the referenced Publication node. When I search on terms/text on the Publication nodes, I want the Dataset nodes to appear. Thanks!
