Re: HELP...compiling first program for lucene Indexer.java

Stephane Nicoll
Field.Text has been deprecated and removed a while back. You probably
found an old code sample on the Internet that is not applicable
anymore to 2.3

Just create your Fields wiht the constructor:  new Field("....")

See the Javadoc for details.
