Subject Re: java.io.IOException when trying to list terms in index (IndexReader)
Date Sun, 02 Aug 2009 03:38:13 GMT
Hi,

I changed the beginning of the try to:

		try {
			System.out.println("About to call .next()...");
			boolean foo = termsEnumerator.next();
			System.out.println("Finished calling first .next()");
			System.out.println("About to drop into while()...");
.
.
.

and here's what I got when I ran the app:

Index in directory :[C:\lucene-devel\lucene-devel\index] was opened successfully!
About to call .next()...
** ERROR **: Exception while stepping through index: [java.io.IOException: The handle is invalid]
