Hi david,
What I want to do is:
if the index file exist, append document
if the index file does not exist, create a new , empty index file.
Please check Lucene api for IndexReader...
It has one method which u can use before opening
IndexWriter..."indexExists(Directory directory)"

Subject: Re: How to open IndexWriter to append document?
Thanks, I think I did not describe my problem exactly.
What I want to do is:
if the index file exist, append document
if the index file does not exist, create a new , empty index file.
How can I implement that?
Appreciate your help!

You should instantiate the writer with create=true :
IndexWriter(store, StandardAnalyzer, True )
Because with create=False, an existing index is expected.
