func main() {
    c := solr.Config{}
    solrClient, err := solr.NewClient(c)
    if err != nil {
        log.Fatal(err)
        return
    }
    if err := solrClient.IsUp(context.Background()); err != nil {
        log.Fatalf("Solr is not up %v", err)
        return
    }
    log.Println("Solr is up")
    solrClient.UseCore(coreName)
    if status, err := solrClient.DefaultCore.Status(context.Background(), false); err != nil {
        log.Fatalf("Check core status failed %v", err)
