[Photon] Next steps

[Yohan Boniface]

Next sprint in Paris this Thursday evening :)
We will focus on finishing the "positive scoring" branch. I'm confident 
we can reach a stable state.
I think I will dedicate some time on Thursday to prepare everything, and 
on Friday to finish.
Christoph, if you have some time Thursday or Friday, we can do a pair 
session so I explain you everything we have done yet on the search logic.

Nonfuzzy results in first, third, fifth place whist fuzzy results in second, fourth ... I'll give it a try. Same could be done with location bias.
