Re: updating Lucene Index

[Otis Gospodnetic]

I haven't followed the whole thread, but this looks weird:

      reader = reader.open(dir);
     if (reader != null) {
        reader.open(index_path);

reader.open called twice?  Why?

Also, you'll get more help on [EMAIL PROTECTED] list.

I tried doing this, but I guess I am doing something wrong. This is my
snippet, can you please let me know what I was doing wrong.

Index_path is the path for the index database
url is the one of the Field in my Documents  I added,

Directory dir = FSDirectory.getDirectory(index_path, false);
      reader = reader.open(dir);
     if (reader != null) {
        reader.open(index_path);
        String tempUrl = ServerName + url;
        Term term = new Term("url",tempUrl);
        reader.delete(term);
      }

Thanks in advance,
Madhavi

You can delete by any unique term, using an IndexReader. I think this
method
is wrapped in IndexModifier as well, not sure. If it isn't, just use an
IndexReader.

yourIndexReader.delete(new Term("yourUniqueField", "yourUniqueValue"));
