line 6:
doc.add(PyLucene.Field("contents", contents, PyLucene.Field.Store.NO,  
PyLucene.Field.Index.TOKENIZED)
change to
doc.add(PyLucene.Field("contents", contents, PyLucene.Field.Store.NO,  
PyLucene.Field.Index.TOKENIZED, PyLucene.Field.TermVector.YES)

assuming PyLucene has ported that symbol. As it is you're not storing  
the term vector of your indexed field. On preview, Andi is right,  
check the lucene lists for questions like these...
