Java – Can I create faceted searches in CT using product attributes?

I was able to create a faceted search using the properties of the variation:

.plusFacets(facets -> facets.allVariants().attribute().ofString(sizeDescriptionAttribute).allTerms())

But if I want to mix product attributes with variation attributes, I haven’t managed to do the same yet.

Is it possible to do this?

You can build more complex processes using the a -> {} syntax. For example:

.plusFacets(facets -> { 
    Object variants = facets.allVariants().attribute().ofString(sizeDescriptionAttribute).allTerms();
    Object products= searchForProducts(fecets);
    return mixOf(variants, products);
}).doMoreStuff();

So this will give you a combination. You just need to implement the missing method or use a similar syntax.
