Personally, I greatly prefer to view results as posts than as topics. My typical search experience on other forums is to search for a keyword, realize that topic view was default, click back change it to posts, wait for search flood limit to pass, and then search again. To me getting a list of topics back isn't very useful because you don't know the context of the result, seeing the post lets me figure out if it's even related to what I'm looking for, before I click into the topic.
Again, that's just my personal view, if we find that most people prefer a topic listing, we'll change it or introduce a setting perhaps.
