"searched"? The node I referenced contains "poll" and "suggest" so you either didn't use Super Search or you didn't finish searching (or...).

The search box at the top of each page isn't very useful for finding material by subject matter as it only searches titles (perhaps it should be called "find" instead? -- gee, this fact isn't clearly noted at all, is it?).

Since your question was about the site, select "PM Discussion" in Super Search to make the searching much faster. Hope that helps.

I've started patching the search results page in hopes of making some of this much clearer.

Yep, the search box is what I used. I sometimes use Super Search if I want to find something in a particular section. I never knew that the searches worked differently.

I suggest you add a disclaimer to the title search.
