The page summary doesn't include some of the words, and worse is that when you go to the page, and hit ctrl-f, you can't even find one of the omitted keyword! Frustrating as hell.
I think this has been around for a while. I usually went to the cached version which highlights the searched terms in different colors. At the top, the omitted terms are listed and described as appearing only in sites linking to the current site. This may even be very helpful in finding sites. However when you specifically search for one of those words (say, a configuration parameter) it just sucks.
DEFENDER played in the favicon.
Why the main article this summary is about is not linked is beyond me...
We don't really understand it, so we'll give it to the programmers.
