Some search suggestions I got on enwikinews:
:Comments:Curfew imposed in Jammu and Kashmir, three injured and four killed/Comments from feedback form - "security men? i think u mean p..."
:Comments:Hong Kong 'tutor king' applies for bankruptcy/Comments from feedback form - "nice.."
They should be prefixed with Thread.
I got these when I started typing Comments into the search box (So really its questionable if thread namespace things should show up at all).
If I start typing thread into the box, I get the pages being prefixed with "thread:" as appropriate.
