Rendering does happen in the thread for the search, but I guess people
won't notice a difference in performance normally. The other place
where stemming happens is the word frequencies, but in the UI that is
done as a comet snippet and pushed on demand, so there shouldn't be a
noticeable delay.

stuff to the companion object. Of course, suggestions are welcome, but
there's always room for improvement later on.
