There's a project out there called LIRE (I heard about it on this list) that's
supposed to create a lucene-based CIBR index for images. I wonder if this
could be integrated with Solr? Personally I don't really care about the flower

So the index fields look like (50% #00, 20% #99):
color: #00
color: #00
color: #00
color: #00
color: #000
: extraction algorithm, etc.) So, for a product with 50% of #00, and 20%

Thanks for all the replies. I think creating 10 fields and feeding each
field with a color's value for 10% from that color is a reasonable approach,
and easy to implement too. One problem though, is that not all products have
a total of 100% colors (due to various reasons including our color

This discussion is incredibly interesting to me! We solved this
simply by indexing the color names, and faceting on that. Not a very
elegant solution, to be sure - but it works. If people search for a

If it were just a couple of colors, you could have a separate field

and then you could use a function query to influence the score (or you
could sort by the color percent).
However, this doesn't scale well to a large index
