The main issue is that it shows bunch of completely unrelated results. It's not like the other channels are match in any way - i just checked and out of 3888 public-ed channels (as of tonight), there is only 1 that has "tangrams" in its metadata.
A second issue is the instability of the search - sometimes it shows the single correct match on top of the list, otherwise - at the end. Press refresh a few times, enjoy situation changing. It's more of a fishy smell, symptom of a bigger problem
