@Jspoelstra Yes, I agree redirects with ids should not be filtered/altered in search suggestions. I can't say it's something I can definitely do as it's not my decision, but I can state my opinion :)

The other problem is that search suggestions aren't a lot of good when the default search directs the user to Special:Search, instead of the go-search functionality found in vanilla MediaWiki. It's all well and good finding the right page from the suggestions, but when you end up on a search results page it's a bit pointless.
