: What stops you from using the reader before you add the document to the : index? That doesn't really help people who want to use the same reader for two different fields (ie: with different analyzers) I've never accutally used a Field based on a Reader, so it's never occured to me to wonder who is responsible for closeing the reader -- I agree, it's strange, and not what i would have expected either. Looking at the code, it seems really hairy. I can't see any actual garuntee that any Reader (including the StringReaders opened under the cover when you make a Field using a string) will/won't be closed -- if you use an Analyzer that comes with Lucene, they all seem to use the Tokenizer class (in one way or another) and *it* is what closes the Reader when it gets .close()ed -- but there is no reason to believe that any existing of future third party analyzer will use that class, the API just requires that they provide a TokenStream (the superclass). TokenStream's .close() is abstract, so people are free to write Analyzers that don't close the Reader's they get. I can't think of any clean way to change this without causing lots of backwards compatibility problems for lots of people. : -----Original Message----- : From: Beady Geraghty [mailto:[EMAIL PROTECTED] : Sent: Thursday, September 15, 2005 2:30 AM : To: java-user@lucene.apache.org : Subject: input reader closed after IndexWriter.addDocument(doc) : : am new to Lucene.
