If I try to search for games like "two point hospital" then the search changes my request to:
"two%20point%20hospital" which results in 0 results.

This way I cannot search for games or other stuff containing blanks.
I also tried to mask it using " but did not work.

I am using:
Windows 10, Microsoft Edge

It has been broken for years.

Best to use a google site search instead.

Yeah, that's been a persistent bug for at least a decade.

A few years ago it was working, one day it suddenly stopped working, and as usual they never fixed it.

It was 2008, the year of Our Lord, when emperor GOGBearanious the V-th declared whitespace to be heresy in all forum searches. To even attempt using one is both brave and foolish!

Yeah, unfortunately, that's the case for quite some time now.

Very recently, I created a thread titled "Ever wondered?"
Out of curiosity, I "tried to find it" via the forum search.

If I only search for "ever", the search returns 199 topics.
The best of all? In this case, my thread isn't even listed in the search results.

If I only search for "wondered", the search returns 101 topics - and my thread is displayed on the second position from top.

And of course:
if I search for "ever wondered", the search returns the message: "ever%20wondered" returned 0 topics.
