Just wanted to mention I think I found a bug with highlighting; not exactly sure the cause, but it's very easy to reproduce if you'd like to have a look:
->visit my site (http://www.justin-klein.com)
->search for "justin-klein.com 2.0" (the search box is at the upper right)
->view the first result (the post is called "Justin-Klein.com 2.0").
You'll notice that it's highlighting a bunch of "2"'s in the content, that aren't actually there; I'm thinking it has something to do with htmlentities or the like. For instance, wherever there should be an apostrophe, it shows "217;", with the "2" highlighted.
Just an FYI :)
