You would need to index it for this to work.
From javadocs for IndexReader.deleteDocuments(Term):
Deletes all documents _containing_ term
Containment relates to indexed terms.

Ismail,

I was having the same type of problem (using v2) until I changed
my index to change the ID field from Field.Index.TOKENIZED to
Field.Index.UN_TOKENIZED. Can you try that, or create a secondary field
that is set up that way with your pk id in it?
