On the same search that you have performed. The result is 3 products:
Demosthenes, Greek Hermes and Xi. Please check the 3 links below. None of this products has a variation that is red fur. The fur come in other colors and the red color come in other textures.
When I set up the search widget I use the AND for Query type.
