Not sure if this is the right thread to post in...
It seems to be common lately to encounter error pages (using explorer 7) when doing searches, especially the advanced searches and searching specifically in the forums or threads using the appropriate tabs.
A reason I post here is because many posters become irritated with duplicated thread topics, and start entire discussions on the subject. But when search does not work properly, it seems difficult to avoid these issues...
This is not a rant... I don't claim to have the answer and solutions, and I am sure the technical staff are doing their best.
