[Plugin: Search Regex] No Comment content search on WP 3.4?

I can’t say it’s whatever is happening in your particular case(especially since I have no comments data myself), but you might want to have a look at my recent thread, where I’m finding some strange behavior with the “Limit to” option. It’s messed up enough I’m paranoid it’s a “just me” thing, so if it looks familiar it’d be great if you could confirm over there.

That’s incredible! It behaved just like you said:

no limit – no results
10 – no results
25 – 3 results
50 – 10 results
100 – 22 results

What can we do now?

The only thing I can see working at the moment is to add a large value to the drop-down. I mentioned where to do it in my original post. It’s pretty simple.
