Steps to reproduce:
I was searching for "CVE-2023-4863" (without the quotes) in region International.
One of the links was https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-4863 and presented without description (most likely cause a robots.txt forbids access)

After clicking "More results", the exactly SAME result (URL was identical, byte for byte) showed up again, this time with a "We would like to show a description here..." text

Expected behavior:
Prio 1: No duplicate result
Prio 2: It's strange the handling of sites with blocks in robots.txt sometimes leads to missing descriptions, sometimes to some kind of fallback text
Prio 3: Result hit should maybe rank lower or not at all if there's enough other hits
Debug info:
