I thought about that but I opted for simplicity of first picking the exact matches. I was unsure about the usefulness of relaxed matching to begin with. But I now realize that to see how useful that would be we need to experiment it and a matrix approach would become necessity for that.

I'd rather keep that file as is for later merge with Nico. It came from the delitification patch and I tried to keep the new files as they are.
