Just tested the search results here... and for me they're still broken. 100% reproducible too.
It's easy to reproduce, so I'll give the steps here.
1. After logging in (as I haven't tested today when not logged in), type "Mellanox" into the simple search field in the top right area (under the username info).
2. This will show a page of results to do with "Mellanox". The search results here all work. eg middle clicking a result will open it in a new tab, and the new tab loads the correct page.
3. Scroll to the bottom of the search results page, and go to page "2" of the results (or any page after the first).
4. Although the search results on this page look ok, none of the links are correct. Middle clicking any of them just opens a page which never loads (eg blank page).
It seems like the generated url for search result pages after the first one are wonky, so gives blank pages. Maybe some template page needs tweaking?
Hopefully that's useful for getting it fixed, as it's been annoying for a long time. ;)
