Hello Kelly,
I am not entirely sure if i understand your problem correctly. But i believe your first approach is the right one. Your question: "Which products are available that contain skus with color Green, size M, and a price of $9.99 or less?" can be easily answered using a schema like yours. id = 1 color = [green, blue] size = [M, S] price = 6 id = 2 color = [red, blue] size = [L, S] price = 12 id = 3 color = [green, red, blue] size = [L, S, M] price = 5 Using the data above you can answer your question using a basic Solr query [1] like the following: q=color:green AND price:[0 TO 9,99] AND size:M Of course, you would make this a function query [2] but this, if i understood your question well enough, answers it.
