Underwhelmed; I tried half a dozen or so searches. Not impressed. For example, a search for "mead" returns one result. A search for "steriogram" finds none (there should be at least one video by them I've shared). Doesn't appear capable of searching for a literal phrase - "circus of heaven" yields heaps of posts containing the word "of", it appears. Searching for the phrase without the quotes does not appear to prefer them in combination; lots of circus posts but not the one I was thinking of, while Google has the one I wanted first.
There was a uri-encoding issue that seemed to mess up a lot of the results, so now we at least return more than one result for queries such as "mead". I'll work on adding literal searching and perhaps removing common articles next.
