Hi, We're running an e-commerce site that provides product search. We've been able to extract colors from product images, and we think it'd be cool and useful to search products by color. A product image can have up to 5 colors (from a color space of about 100 colors), so we can implement it easily with Solr's facet search (thanks all who've developed Solr).
The problem arises when we try to sort the results by the color relevancy. What's different from a normal facet search is that colors are weighted. For example, a black dress can have 70% of black, 20% of gray, 10% of brown. A search query "color:black" should return results in which the black dress ranks higher than other products with less percentage of black. My question is: how to configure and index the color field so that products with higher percentage of color X ranks higher for query "color:X"? Thanks for your help! - Guangwei
