When you use hits.doc(i).get("content") lucene tries to retrieve the content
of a field, but you can only get stored (saved) fields. Since you do not
store the content you can not get it's value. The field you use is only
searchable (indexed) but is not stored, this is why you can't get the
field's value.Aviran -----Original Message----- From: Haipeng Du [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 14, 2004 11:51 AM To: [EMAIL PROTECTED] Subject: RE: I am new to lucene Thanks Aviran. But how could I use content to search the document if I use Field.Text("content", reader). I do not want to save the document content . Thanks a lot.
