Yes, there is always a plan and room for improvement. Stefan Stromqvist already feedback on this earlier. And we have search functionality improvement on the top in development wishlist. Next year you can see some improvement there.
Bytheway there are some tips and tricks for searching something specific. Like searching something specific always get accurate result. e.g searching on '800xA system microsoft patches updates'. then recommended to just write a word microsoft and you get required info filtered around microsoft - word.
if you want to filter search result on system, then use add(+) e.g. you want to search for system diagnostics information in Freelance. Then if you just write word diagnostics in search box you get related threads where diagnostics word appears. instead you can search this way 'diagnostics + Freelance' you will get most of the threads around Freelance system in search result. and just for confirm it works this way you can also try 'diagnostics + 800xa' and you will get search result around system 800xA.
moreover I have seen few people they find 2-3 years back question and comment there that how you resolved this problem. means they are able to search something related to topic they are looking for.
And if you want to search complete question than search results are not good but we have google there.
Thanks for your feedback. and keep browsing and participating on AKS.
