Etienne commented on LUCENE-463:
--------------------------------

Hi, 
Thanks all, 

I think everything works well now. This way to make a sort is not mention in the \
Lucene In Action book. Maybe it should be a bit more detailled there.

public Sort createSorting(ILuceneFilterParameterVO vo){
		String fieldToSort = vo.getSort();
		Sort sorting = null;
		if(fieldToSort!=null&&!fieldToSort.equals(LuceneConstants.NOSORT)){
			// descending is the default setting for our requierements.
			boolean reverse = (vo.getSorder().equals(LuceneConstants.ASCENDING))?false:true;
			SortField sortField = new SortField(fieldToSort, SortField.STRING, reverse);
			sorting = new Sort(sortField);
		}
		return sorting;
	}

Thanks all.

Etienne.
