There is no sample code for doing that but it's quite straightforward - if
you know you indexed some dimensions under different indexFieldNames,
initialize a FacetCounts per such field name, e.g.:
FastTaxoFacetCounts defaultCounts = new FastTaxoFacetCounts(...); // for
your regular facets
FastTaxoFacetCounts cityCounts = new FastTaxoFacetCounts(...); // for your
CITY facets
Something like that...
