   Hi,
   its better to add your id field with the correct type like this:
   
   `doc.Add(new Int32Field(IdFieldName, thumb.Id, Field.Store.YES))`
   
   when you want to query by the id use this to generate the term:
   
   ```
   var bytes = new BytesRef(NumericUtils.BUF_SIZE_INT32);
   NumericUtils.Int32ToPrefixCoded(id, 0, bytes);
   var term = new Term(IdFieldName, bytes);
   ```
