Hi, Sure, you can use filters and facets for this. Start a query with ...&facet.field=source&facet.field=topics&facet.field=type When you click a "button", you set the corresponding filter (fq=source:people), and the new query will return the same facets with new counts. In the Audi example, you would disable buttons with 0 hits in the facet count.
