I have a type 'projects' referencing two other types ('kustomer','products') via entity reference. Now I want to implement a drilldown search. I therefore use search API with facete api. I build a index and a view for Type 'project'. The filtering works well on this view. I have facetes for types 'customer' and 'product' and can filter.
The target is a workflow where you start at a list of 'products'. When you select one you will get a list of 'customers' where a 'project' exists that contains that 'product'. After that you select a 'customer' and you get a List of all 'project's having that 'product' and 'customer' preselected as facetes.
Can someone point out a module or configuration that does that? Thanks in advance Clemens
