BibLaTeX bibliography not displayed at all

Question

I have a lot of problems with the bibliography.

I read the BibLaTeX manual but I couldn't find a way to fix it.

Here is the source:

\documentclass[]{report}
\usepackage[latin1]{inputenc}
\usepackage{graphicx}
\usepackage[italian]{babel}
\usepackage{csquotes}
\usepackage{biblatex}
\addbibresource{biblio.bib}

\begin{document}
\tableofcontents

\noindent\hrulefill

\section{foo}
\cite{1tree} \& \cite{wiki1}

\noindent\hrulefill

\printbibliography

\noindent\hrulefill

\end{document}

And here is my biblio.bib:

@misc{wiki1,
author = {Wikipedia},
title = {Disuguaglianza Triangolare},
year ={2015},
url ={https://it.wikipedia.org/wiki/Disuguaglianza_triangolare},
} 

@online{1tree,
author = {Universit\`a di Torino},
title = {Definizione 1-Tree, TSP Lower Bound},
date = {date},
url = {http://www.di.unito.it/~locatell/didattica/ro2/TSPnewbound-sl.pdf},
}

And this is the output:

Foo

I would also be able to use

\defbibfilter{online}{ type=online }
\defbibfilter{offline}{ not type=online }

and

\printbibliography[filter=online]

What am I doing wrong?

P.S.: I am using TeXStudio with MikTeX

Well, I feel a little bit stupid...I formatted my PC a few weeks ago and forgot to resetup TeX Studio with Biber.. Thanks everyone — Spinnaker, Nov 21 '15 at 13:26
The code (when put together) works perfectly fine here. Are you sure the Biber run completed successfully and all relevant programmes were run sufficiently often? See Question mark instead of citation number. Note that with your current definitions of the bibfilters, you could just use \printbibliography[type=online] and \printbibliography[nottype=online]. — moewe, Nov 21 '15 at 13:28
Does that mean we can close your question as a duplicate of Biblatex with Biber: Configuring my editor to avoid undefined citations. — moewe, Nov 21 '15 at 13:30

The problem might be due to the date format, which should be yyyy-mm-dd. With this format it compiles fine, and the filters work. Don't forget to follow the cycle: pdflatex -> biber -> pdflatex ->pdflatex:

\documentclass[italian]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{babel}
\usepackage{csquotes}
\usepackage{biblatex}
\addbibresource{somebiblio.bib}
\defbibfilter{online}{type=online }
\defbibfilter{offline}{not type=online }

\begin{document}
\tableofcontents

\noindent\hrulefill

\section{foo}
\cite{1tree} \& \cite{wiki1}

\noindent\hrulefill

\printbibliography[filter =online]

\printbibliography[filter =offline]

\noindent\hrulefill

\end{document}

Mhh, with a current Biber invalid date formats are simply ignored. Biber issues a warning about that, but the rest goes through. – moewe Nov 21 '15 at 13:29
You're right. Anyway, I posted before the O.P. explained what really happened. I guess I should withdraw my answer. – Bernard Nov 21 '15 at 13:43

I think this question should be closed since it was about a mis-configuration anyway. Your observation is certainly valid so you might as well let it stand. – moewe Nov 21 '15 at 13:45
