Union may be the best solution, solution, depending on your circumstances on the canvas. I don't use it much, in a situation like this, because it sometimes changes the arrangement of the nodes. And I don't like having the nodes rearranged.
One thing I do sometimes, is drag a selection box around the stack (with Node tool

), and then click "Join selected nodes" button. That only works if the nodes are consecutive nodes on the same path. Overlapping nodes of different paths, or non-consecutive nodes, will not join like that.
If they are either not consecutive nodes, or they are on different paths, here's what I do. Like before, drag a selection box around the stack of nodes (with Node tool

). Then hold the Shift key, while you click once on top of the stack. That deselects the top node, leaving all those underneath still selected. Then just delete. Actually might be best to hold Ctrl key while deleting, especially if nodes are non-cusp/corner nodes.
Edit
The search feature in this forum needs a good deal of tweaking. But even under the best of circumstances, it's often hard to search, if you are new to a program. I've found that knowing the proper terminology is often the only way to search successfully.
