One other slight problem...
It sometimes makes results significantly worse.
More specifically, the "intelligent" prediction routine has a fairly significant flaw from a useful Search (and SEO) point of view, in that hitting 'space' after a keyword reloads the results based on what it considers the most popular *following* word would be, rather than the keywords you've already entered. While this may be intended to save time, it causes problems if you're not sure on the best keywords to use for a result, and trying to refine them as you go.
For example, I needed to find the kanji for the word "japanese" the other day and found myself staring puzzled at pages of results for "japanese knotweed", having not twigged I'd hit space on autopilot. Lost me a good 5 seconds there, I can tell you..
