I'm sure there's some post doctoral types who could get a graphic shape
analyzer, color analyzer, to at least say it's a flower.
However, even Google would have to build new datacenters to have the
horsepower to do that kind of graphic processing.
Not necessarily true. Like.com - which
can you you explain exactly how you are indexing the data and what your
query looks like?
I used the same field name (color), not 10 different names (c0 - c9).
So the index fields look like (50% #00, 20% #99):
color: #00
color: #00
color: #00
color: #00
color: #00
: I used the same field name (color), not 10 different names (c0 - c9).
ah .. got it. then what you are probably seeing is because of length
normalization, if you use omitNorms=true then it shouldn't matter.

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

Hi Guangwei,
When you index your products, you could have a single color field, and
include duplicates of each color component proportional to its weight.
For example, if you decide to use 10% increments, for your black dress
with 70% of black, 20% of gray, 10% of brown, you would index the
Another option would be to extend Solr (and donate back) to
incorporate Lucene's payload functionality, in which case you could
associate the percentile of the color as a payload and use the
BoostingTermQuery... :-) If you're interested in this, a discussion
on solr-dev is probably
If it were just a couple of colors, you could have a separate field
for each color and then index the percent in that field.

grey:20
and then you could use a function query to influence the score (or you
could sort by the color percent).

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
green running shoe they get -green- running shoes.

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
