Ok, the search functionality is the same, but it doesn't show the hint text in the field (at all) when I use Safari 5.1.9 on Mac Snow Leopard 10.6.8. It does show the hint text in Chrome 28.0.1500.71 on Mac 10.6.8 and it does show the hint text as well with Safari 6.0.5 with Mac Mountain Lion 10.8.4. So, it's something with Safari 5.1.9.
But, anyway, as I said, I'm still getting the same poor search results with Chrome and Safari 6.x in 10.8.4 as with Safari 5.x in 10.6.8.
The search results aren't being constrained to my own posts (which is really bad) and keywords aren't really being highlighted, etc. It actually seems to focus more on the topic of the thread than the keywords contained within my posts themselves. Not good for finding old posts.
It's simply hard to make sense of the search results.
