So instead of searching for "Raiders of the Lost Ark", you might just type "raiders ark" and still get what you're looking for as the top result.
That seems practical, but I often find myself typing titles in full anyway. It's like, I would spend slightly more time thinking about what's the fewest key words I can enter to get what I want than just simply typing the whole thing quickly without even processing it.

Depends. On a search like GameFAQs where I know it is indexed and I want to find a specific page I'll use as few words as necessary. When searching for general information I'll probably type the entire title.
