public QParser createParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req) {
    return new QParser(qstr, localParams, params, req) {

        public Query parse() throws ParseException {
            final Double x = localParams.getDouble("x");
            final Double y = localParams.getDouble("y");

            final String fieldPrefix = localParams.get("prefix", tierPrefix);
            final Double distance = localParams.getDouble("dist");
            //GSI: kind of funky passing in an empty string, but AFAICT, it is safe b/c we don't want to assume tier prefix stuff
            CartesianPolyFilterBuilder cpfb = new CartesianPolyFilterBuilder(fieldPrefix);
            //Get the box based on this point and our distance
            final Shape shape = cpfb.getBoxShape(x, y, distance);
            final List<Double> boxIds = shape.getArea();

            //Sort them, so they are in order, which will be faster for termdocs in the tier filter
            Collections.sort(boxIds);
            //Get the field type so we can properly encode the data
            IndexSchema schema = req.getSchema();
            FieldType ft = schema.getFieldTypeNoEx(shape.getTierId());

            //Create the Filter and wrap it in a constant score query
            Filter filter = new TierFilter(shape.getTierId(), ft, boxIds);
            return new SolrConstantScoreQuery(filter);
