Multivalu field grouping

[Darin Amos <da...@gmail.com>]

Hi All,

I sent an email out earlier but I didn’t get any responses so I thought I would try to reframe the question. 

I have a problem that I believe multivalued field grouping is the perfect answer for, of course since SOLR doesn’t support multivalued field grouping, I need to find an alternate approach. Or perhaps someone has found a way to do multivalue field grouping.


My client is an ecommerce firm and lets says they have a category page Where they want to show ALL shirts, but the results are grouped by a subcategory, tee-shirt, sweater, tec.... If he subcategory is a single value field this works fine, but a product document could belong to multiple categories. Perhaps there is a “Popular” or “Trendy” category that a production would also belong to.

My gut tells me this is a perfect fit for grouping on multi valued fields, and I can’t think of another way to solve this easily without finding a completely new way to index.

Thanks!

Darin

*PS: For example, I would want my results returned like the below (simplified):


All Shirts:
	- Trendy
		- Tee Shirt 1
		- Tee Shirt 2
		- Sweater 1
		- Sweater 2
	- Tee Shirts
		- Tee Shirt 1
		- Tee Shirt 2
		- Tee Shirt 3
		- Tee Shirt 4
	- Sweaters
		- Sweater 1
		- Sweater 2
		- Sweater 3
		- Sweater 4
