MultivalueFilter is not working

I am trying to filter test runs based on some test set ids. I have created a multivalue filter for that based on some examples I found in the internet.But while retrieving, this filter is not working. Single value filter is working fine.I have pasted the code for multivalue filter below :

<code>

      List<RemoteFilter> remoteFilters = new ArrayList<RemoteFilter>();

      RemoteFilter remoteFilter = new RemoteFilter();

      MultiValueFilter multiFilter = new MultiValueFilter();

      multiFilter.setIsNone(false);

      multiFilter.setValues(new int[] {59313,59323});

      remoteFilter.setPropertyName("TestSetId");

      remoteFilter.setMultiValue(multiFilter);

      remoteFilters.add(remoteFilter);

      RemoteFilter remoteFilterArray[] = new RemoteFilter[remoteFilters.size()];

      RemoteTestRun[] nextChunk = spira.testRun_Retrieve(remoteFilterArray, new RemoteSort(), rowNum, chunkSize); 

</code>

If you find anything wrong with the code or anything I am doing wrong then let me know.

Thanks.
