How do i speed up reading Lucene search results

Reading lucene search hits results to xml VERY slow. How do I speed it
up?  Yes I have to read them to xml.  I also can't find a way to
convert the hits object directly to xml.  So now what?
Since there is no direct way to read it to xml, I have to first
convert the hits to a dataset then to xml. Here is what I am doing...

  // execute the search
  Hits _oWidgetHits =
_oLuceneIndexSearch.ExecuteSearch(_booleanqqueryWidgetsQuery,
INDEXPATH);

  // read hit results
  if (_oWidgetHits.Length() > 0)
  {
    for (int iResultsCount = 0; iResultsCount < _oWidgetHits.Length();
iResultsCount++)
    {
      // get the do***ent from index
      Do***ent _dResultsDoc = _oWidgetHits.Doc(iResultsCount);

      // create a new row with the result data
      DataRow _rWidgets = _dtSearchResults.NewRow();
      _rWidgets["WidgetID"] = _dResultsDoc.Get("WidgetID");
      _rWidgets["WidgetTitle"] = _dResultsDoc.Get("WidgetTitle");

      // add row
      _dtSearchResults.Rows.Add(_rRecipe);
    }
  }

  return _dtSearchResults;

I have tried using the hitIterator but that give me no gains.  I am
researching the hitCollector but that seems to be the same concept.

The issue is the hits object really doesn't help.  What I need is an
xml object.  So I convert the hits to a dataset and that to xml.  To
complicate things, the term searched in my boolean query is returning
32,000 records. Do I need them all?  Probably not but I have to return
them in my webservice.
