We have an extra ~2.5k rated search results from image-recommendation-test, so we should probably re-tune our search results with these added to our training dataset.
erm ... I (@Cparle) probably will have to do this, seeing as I did the original search tuning and can re-do it without too much effort, but in the process I ought to make the process easier for anyone to do
 a new set of parameters for search signals to be used in the search profile
- an easier to follow process to generate those parameters
