Of course! I simply had to test this while working on [bug 4988] (http://bugs.dwscoalition.org/show_bug.cgi?id=4988)  (english-stripping /search). Part of the bug is rephrasing the search comment box to make it clear that you can only search in paid journals. I didn't understand how it worked at first so I did some searches with my usual seed account and a free test account. It turns out that site search and journal search work differently: site search only lets you search for comments if your account is paid and will only search in paid journals but journal search lets everybody search for comments in paid journals (which is one of the main benefits of having paid comm; I remembered that afterwards). Ironically I'm currently stuck on my bug because I have to differentiate between the four different situations, and Jen commented to say you were making a method which could be useful for my bug (it definitely will), which is why I looked at your pull. :)
