The requirements are: Search Result web part 1 shows all master elements ( e.g buildings ) , once a building is selected then Search Result web part 2 should show all equipment in that building.
I plan on using two Search result web part and two Search boxes related to those results web parts. An alternative could perhaps be the tweak the control and item display of a single results web part or use the hover panel to show the equipment.
Any ideas on the best way to proceed? Thanks
