Any suggestions on how to apply selections to groups of results instead of the entire list?

[Aston77]

When I run searches across large groups of images (say 100k) it is not uncommon for the search to return 1000+ results, of images that need to be manually reviewed.

Is there a way to select blocks of results and apply selection filters like "select all" or "all except the biggest"?

Generally, I apply a base selection to the list and then cycle through the list with the arrow key and make adjustments to the already selected list for when it has selected the inferior version since clicking 1000+ check boxes individually is tedious.

If I could select groups I can work through them in blocks/pages as opposed to one large list.
